21 Bikini Brands Like Triangl for Stylish Beachwear
You bought the neoprene bikini, wore it on three holidays, and now every photo on your camera roll shows the same colour-blocked triangle top. The fit was good. The problem is that Triangl does one thing, and once you have two sets there is nowhere left to go inside the brand.
These 21 swim labels cover the ground Triangl leaves empty. Some match its bright, structured look at a lower price, some fix the support problems it ignores, and a few take the same clean line somewhere considerably more expensive.

Frankies Bikinis
Frankies Bikinis is a California swim label built on flirty cuts and print-led drops, with bikini tops from $95 to $150 and bottoms from $90 to $115. Triangl sells you graphic colour blocking. Frankies sells you metallics and ribbed textures, plus collaboration collections with KHY and Paige Lorenze.
Frankies sells tops and bottoms separately, so a $95 triangle top with a $90 skimpy bottom lands near the price of one Triangl set. Coverage runs cheeky by default across most of the range. Our guide to swim brands like Frankies goes deeper if this is the direction you want.
Best for: Trend-driven sets you see on your feed before you see them in a shop.
L*Space
L*Space makes soft-handle bikinis and one-pieces in a California register that runs quieter than Triangl's neon. Collections arrive as named drops such as Paradise Island and Heatwaves, with separates split across dedicated tops and bottoms pages so each half is sized on its own.
Pricing sits in the premium bracket, above Triangl. The fabric reads matte and substantial next to neoprene, and the palette stays muted where Triangl shouts. Try it if the Triangl fit worked but the colour stopped feeling like you.
Best for: Sophisticated solids once the neon has run its course.
Solid & Striped
Solid & Striped works in stripes and gingham, with retro-leaning cuts that read more Riviera than pool party. The bikini range covers tops, bottoms and one-pieces at premium prices.
Solid & Striped reads like a 1970s postcard next to Triangl's pool-party brightness, all high-cut legs and squared necklines. Buy it if your holiday photographs happen in Positano rather than Palm Springs, and if you want a suit that still looks right in five summers.
Best for: Classic stripes and solids that skip the trend cycle.
Kulani Kinis
Kulani Kinis is an Australian brand selling bikini tops from $66, which makes it the cheapest close match to Triangl here. Styles like the Halter Bralette ($66) and the Lettuce Edge Bralette ($69) come in seasonal print families such as Monaco Whispers.
The fabric is soft rather than structured, so it packs flat and dries fast. You lose the moulded shape neoprene holds. You gain three sets for the price of one, with free returns and exchanges taking the risk out of sizing blind.
Best for: Buying several sets without agonising over it.
Hunza G
Hunza G sells one-size swimwear in its Original Crinkle fabric, priced from £175 to £215. The crinkle stretches across a wide span of bodies, which is why the brand skips conventional sizing altogether.
Triangl holds its shape through neoprene. Hunza G holds yours through the memory in the yarn. Silhouettes are 1980s: square necks and wide straps. The range extends to swimsuits, higher-coverage styles and collaborations with Burberry and Swarovski. It is the biggest price jump in this part of the list and the piece most likely to still fit in three years. See our Hunza G alternatives for more in this vein.
Best for: One suit that keeps fitting through body changes.
Marysia
Marysia is the scallop-edge brand, founded by Marysia Reeves and built around one recognisable trim that runs across nearly every style. Bikini tops cost $159 to $199, bottoms $149 to $199, and one-pieces $369 to $395.
Triangl signals through colour. Marysia signals through that scalloped seam instead, so the shape does the work the colour usually does. The brand plants a tree per order and describes eco-friendly production across the range. Sport and maternity lines sit alongside the main swimwear, which means the scallop follows you through more than one stage of life.
Best for: A recognisable design detail with no logo attached.
Seafolly
Seafolly has been making swimwear on the beaches of Sydney since 1975, with tops and bottoms both around AU$90. The catalogue is the broadest on this list, running from full-coverage one-pieces through string bikinis to girls' sizes.
Triangl asks you to like one look. Seafolly lets you choose. One-pieces, resortwear, accessories and girls' sizes sit next to the bright prints, which matters if you swim rather than sunbathe. Five decades of fit data show in how the straps sit under load. Our Seafolly alternatives guide maps the wider Australian field.
Best for: Swimming properly, in a size and cut that behaves.
Monday Swimwear
Monday Swimwear prices bikini tops at $99 to $111 and bottoms at $91 to $97, with one-pieces at $195. Founders Tash and Devin built the label around fit for fuller busts, and the sizing shows it: PP through VVV instead of S, M, L.
That sizing system takes a minute to learn, then solves the problem Triangl left alone, which is a top that supports a D cup without four straps and a knot. Collections such as Signature and Espresso keep the palette warm and plain. If you have given up on triangle tops staying where you put them, start here.
Best for: Fuller busts that need structure, not more strings.
Vitamin A
Vitamin A is a California swim label built on recycled and organic fabrics, with an under-$135 edit on its own site for the cheaper end of the range. Beyond swim it sells linen, knitwear, cotton beachwear and accessories.
Vitamin A cuts cleaner lines than Triangl and takes its colours from nature rather than a highlighter pen. Sustainability is the whole argument, down to a cotton swim capsule made at 98% cotton. Prices sit in the premium bracket, so treat this as the grown-up version rather than a like-for-like swap.
Best for: Sustainable swim in colours that behave themselves.
Bamba Swim
Bamba Swim is an Australian label cutting 1980s-inspired swimwear from 100% recycled materials, with bikini tops at $79 to $89. High legs and thin straps make it the closest thing here to Triangl's confidence without the neoprene.
Collections carry names like 80s Homage, Tropique, Villa Tasca and Born in Brazil, so the print families turn over fast. Coverage is minimal across most styles. If Triangl already felt like a lot, this will feel like more.
Best for: High-leg 1980s cuts in recycled fabric.
Agua Bendita
Agua Bendita sells hand-embroidered swimwear with bikini tops from $120 to $250 and bottoms from $95 to $125. Founders Mari and Cata built the label on handwork, and the embroidery explains why one top can cost as much as a whole Triangl set.
Nothing about it is minimal. Pieces arrive fully embroidered, often reversible, in patterns that look painted rather than printed. Triangl is graphic and flat. Agua Bendita is textured and busy. Buy one piece and keep it for a decade, because it will not date the way a seasonal print does.
Best for: Handworked detail no print run can copy.
Luli Fama
Luli Fama has been making Miami swimwear since 2003 from its base in Doral, Florida, and the scrunch bottoms and wavy-edge trim are its fingerprint. The range runs to resortwear, cover-ups, activewear and girls' swim alongside the main bikini collections.
Triangl keeps its lines straight. Luli Fama ruches, gathers and reverses, so one set gives you two looks. Colour arrives in tropical brights and Caribbean-influenced prints. Pricing sits in the premium bracket above Triangl, and the fit runs small and cheeky by design.
Best for: Reversible sets with ruched, body-skimming bottoms.
Montce
Montce prices bikini tops at $96 to $158 and bottoms at $92 to $138, with a fit-first approach visible in how many strap and tie variants each style carries. Drops rotate through seasonal collections, with a permanent Core range underneath them.
The overlap with Triangl is the clean modern line. The difference is finish: knotted straps and adjustable ties, plus a collaboration line with Elsa Hosk. Buy from Core if you want the fit without committing to this season's print. Our Montce alternatives guide compares the nearest rivals.
Best for: Adjustable straps and a core range that stays put.
Same Los Angeles
Same Los Angeles sells swim tops at $128 to $158, bottoms at $108 to $118 and one-pieces at $258 to $378, plus a ready-to-wear line of dresses, denim, gowns and jewellery. It is the most fashion-led label here.
Triangl designs for the beach. Same designs for the photographs taken near it, then sells you the sarong and the jewellery to finish the look. Free domestic shipping starts at $300, which tells you the expected basket size. Treat it as the brand you buy once, for a specific trip.
Best for: A whole swim-and-resort look bought in one order.
Sommer Swim
Sommer Swim cuts minimal bikinis from Italian Lycra and finishes them with custom gold-plated hardware. Tops come in triangle, halter, balconette and bralette shapes, with bottoms sold separately.
That Lycra is the whole difference between Sommer Swim and Triangl. It sits closer to the skin and drapes instead of holding a shape, which reads European beach club rather than pool party. Pricing is premium, and the gold hardware is most of what you are paying for.
Best for: Slinky Lycra sets with gold hardware.
Beach Riot
Beach Riot puts festival energy into swimwear, with roughly 100 styles across its swim range at mid-range prices. Sparkle fabrics, high-shine finishes and loud collaboration prints carry it.
Beach Riot is bold in a way Triangl avoids, and the tops end up worn to dinner more often than swimwear usually does. Activewear sits alongside the swim, so a bikini top with a matching legging is a normal purchase here.
Best for: Swim you can wear to dinner without changing.
Blackbough Swim
Blackbough Swim builds its range around seasonal print collections with names like Sun Stripe, Costa Limone, Dolce Far Niente and Al Fresco, each landing as a complete family of tops, bottoms and one-pieces at premium prices.
Blackbough Swim is the closest match here to Triangl's internet-native model: drop-based, colour-led, sized for mixing across a collection. Coverage runs from bandeau through triangle, so one drop can dress two people who want opposite amounts of fabric. If buying into a season rather than a single piece was the appeal, this repeats it. See our Blackbough alternatives for the wider set.
Best for: Buying a whole colour story in one go.
Aqua Blu
Aqua Blu is an Australian swim label selling bikini tops around AU$115 and bottoms from AU$100, with DD/E cup one-pieces at AU$220. Collections land as full print stories such as Scarlet and Bronze, covering triangle tops, high-waist pants, classic pants and cross-front pants in matching fabric.
Triangl gives you a block of colour. Aqua Blu gives you a print, usually a large one, cut for a body that needs support underneath it. Cup-sized styles and more than 500 products in the swim range make it the most practical pick here above a C cup.
Best for: Cup-sized swim in a statement print.
Tropic of C
Tropic of C sells eco bikini tops and bottoms at $95 to $125, with two-piece sets bundled at $180. Candice Swanepoel fronts the campaigns, and the range splits by fabric into eco, C and luxe lines.
Tropic of C cuts skimpier than Triangl and runs earthier on colour. Recycled fabric is the selling point, spelled out in the brand's own fabric guide. A Victoria's Secret collaboration line gives you the same silhouettes at a different price if the main range is a stretch.
Best for: Recycled fabric in earth tones.
Tori Praver
Tori Praver prices bikini tops at $110 to $147 and bottoms at $94 to $127, working in smocked textures and soft, surf-influenced shapes. The Lani Top ($125) and the Valerie Bottom ($99) show where the middle of the range sits.
Tori Praver is gathered and soft where Triangl is smooth and structured, with smocking doing the work elastic does elsewhere. Popular styles sell out and stay out, so buying on sight matters more here than with the bigger labels. A children's swim range runs alongside the main collection.
Best for: Smocked texture with a surf lean.
Karla Colletto
Karla Colletto is the luxury end of this list, with one-pieces from $366 to $405 and the Tess bandeau at $348. The label has been cutting swimwear for over 25 years and sells by collection name instead of by trend.
Karla Colletto is where Triangl's clean line goes when it grows up and gets expensive. Construction carries the price: support built into the seam, bonded edges, fabric that survives chlorine. Free shipping starts at $200, which is one item. Buy it once, then stop shopping for swimwear for a decade.
Best for: A single swimsuit treated as a ten-year purchase.
How to Choose the Right Bikini Brand for You
Work back from what made you buy Triangl in the first place. If it was the colour, Bamba Swim and Beach Riot carry that energy forward at a similar price. If it was the fit, Monday Swimwear and Seafolly handle support better than Triangl does, and Hunza G removes sizing from the argument entirely.
Budget sorts the rest. Kulani Kinis undercuts Triangl outright at $66 a top. Frankies Bikinis, Montce, Tropic of C and Blackbough Swim sit level with it. Karla Colletto and Same Los Angeles ask you to spend three or four times more for construction that outlasts the trend. Buy one piece from a new label before committing to a set, because swim sizing varies more between these brands than the size label admits.
