Spanx is known for durable, high-performance underwear that offers firm shaping and support, often with a more compressive feel. In contrast, Skims prioritizes all-day comfort, seamless invisibility, and an extensive range of skin-tone shades, using softer, stretchier fabrics that mold to the body.

Let's compare everything you need to know to choose the right underwear for your needs.

Spanx: The Original in Shaping & Support

Founded in 2000, Spanx built its reputation on creating innovative shapewear that smooths, lifts, and supports. Their underwear line extends this philosophy, integrating reliable shaping technology into comfortable, everyday designs. The typical Spanx customer is looking for functional, high-quality undergarments that provide a sleek silhouette under any outfit, from office wear to evening dresses.

  • Product mix: Features styles with integrated shaping, including high-waisted briefs, seamless panties, and control shorts designed for varying levels of tummy control and smoothing.
  • Price point: Generally ranges from $20 to $50 per pair. A premium price for high-performance shaping and durable materials.
  • Quality & Materials: Utilizes durable fabrics like nylon and elastane engineered for firm support and longevity. The construction is focused on holding you in without sacrificing too much comfort.
  • Sizing/Fit: Sizing runs from XS to 3X and is typically true to size, but expect a compressive fit designed for shaping. Always consult their size chart for the best results.
  • Style & Aesthetic: The collection is minimalist and functional, offered primarily in neutral tones like black, white, and beige. The look is classic, sleek, and focused on function over trends.
  • Return policy: Typically offers a 30-day return window for unworn items with tags attached, making it easy to find the perfect fit.

Spanx is the go-to for shoppers who prioritize noticeable shaping, firm control, and durable construction in their underwear.

Its underwear is designed for an ultra-comfortable, seamless fit that disappears under clothing, making it popular for everyday wear.

Spanx vs. Skims Comparison

Price Comparison

Both brands occupy a similar mid-range, premium price point. Skims is often slightly more accessible, with core underwear styles starting at $18, while Spanx pairs typically start around $20. A single pair of high-waisted shaping briefs from Spanx might cost $38, whereas a similar style from Skims could be around $32.

Skims runs site-wide sales and offers bundle-and-save options more frequently, which can bring the price-per-pair down significantly. Spanx also offers sales, but they are often tied to major holiday events. Ultimately, the cost is comparable, but Skims provides more opportunities for discounts.

Quality & Materials

This is a key point of difference. Spanx uses high-quality, robust fabrics with a higher percentage of spandex/elastane to provide firm, compressive support. The materials are engineered for durability and maintaining their shaping properties over many washes. They feel secure and supportive.

Skims focuses on innovative, soft-touch fabrics that offer extreme stretch and a lightweight feel. Their popular "Fits Everybody" collection uses a nylon-spandex blend that feels buttery soft and stretches to twice its size without losing shape. Skims prioritizes a flexible, "second-skin" comfort, while Spanx prioritizes structured support.

Fit & Sizing

Both brands are celebrated for their inclusive size ranges. Skims edges out Spanx with sizes from XXS to 4X, compared to Spanx’s XS to 3X. Both brands generally run true to size, but the intended fit is very different and crucial to understand before buying.

A medium in a Spanx shaping brief will feel noticeably snug and compressive because it is designed to hold you in place. A medium in a Skims brief will mold to your body with a gentle hug and a focus on flexible comfort. If you are between sizes, you might size up in a shaping Spanx item but stay true to size for a Skims product.

Product Selection & Style

Spanx has a functional, minimalist aesthetic. Their core offerings are designed as problem-solvers for creating a smooth foundation under clothes. Their color palette is classic, with a heavy focus on black, beige, and other core neutrals.

Skims built its brand on aesthetic appeal just as much as function. The brand is known for its wide spectrum of skin-tone nudes, seasonal color drops, and modern, often trend-setting, designs. While Spanx focuses on what an undergarment does, Skims focuses equally on how it makes you feel and its visible appeal.

Shopping Experience

Both brands offer intuitive online shopping experiences with detailed size charts and customer photos. Skims' website feels more modern and heavily features user-generated content, reinforcing its community and diversity message. It effectively showcases how products look on a wide variety of body types.

Both Spanx and Skims can be found in department stores like Nordstrom, allowing customers to see and feel the products in person. Returns are straightforward for both brands, with typical 30-day windows for unworn merchandise.

  • You want a secure, compressive feel to create a smooth silhouette under structured outfits.

  • You need underwear that is seamless and invisible, even under thin or tight fabrics.
  • Finding the perfect skin-tone match matters to you.
  • You prefer modern, minimalist styles and an extensive, inclusive size range.
