If you've spent any time on Instagram during summer, you've definitely come across a Triangl bikini. Known for its signature color-blocked designs and structured neoprene fabric, the brand nails the sleek, modern, and sporty beach aesthetic that looks amazing in photos.

Frankies Bikinis is the go-to for trendy, ultra-sexy swimwear with a sunny, California-girl feel.

Their pieces share Triangl's youthful, Instagram-ready vibe but trade the minimalist structure for a more bohemian and daring energy. Expect prices to be in a similar range, with tops and bottoms sold separately for around $70-$120 each. If you want swimwear that’s unapologetically on-trend, this is your spot.
