Plus Size Swimwear Guide
Beach days are for everyone. This guide covers every swimwear style - bikinis, one-pieces, tankinis, and cover-ups - with sizing tips and support advice specifically for plus size women.
Plus Size Swimwear Styles
High-Waisted Bikini
The most popular plus size swimwear style. The high-waisted bottom defines the waist, provides tummy coverage, and pairs with a supportive bra-style top. Retro-chic and endlessly flattering.
One-Piece Swimsuit
Classic and versatile. Look for styles with ruching for a smoothing effect, plunge necklines for style, and built-in cups for bust support. Modern one-pieces are anything but boring.
Tankini
A tank-style top with separate bottoms. Offers the coverage of a one-piece with the convenience of a two-piece (easier bathroom trips). Great for active beach days.
Swim Dress
A skirted swimsuit that provides extra coverage around the hips and thighs. Feminine and fun, with built-in support. Works beautifully as a resort-wear piece too.

Finding Your Swimwear Size
Plus size swimwear comes in sizes L to 5XL, depending on the style. Use your bust, waist, and hip measurements to find your size in our comprehensive size chart.
Swimwear sizing tip: Swimwear should fit snugly when dry because it will stretch slightly when wet. If you are between sizes, go with the smaller size rather than sizing up. The fabric will relax in water.
For bikini tops, bra-sized swimwear (e.g. 42D) provides a more precise and supportive fit than S/M/L sizing. If you wear a 42D bra, you will likely wear the same in a bra-sized bikini top.
Support Features to Look For
Underwire or Moulded Cups
Shapes and lifts the bust for a flattering neckline. Moulded cups prevent visible nipple show-through.
Wide Adjustable Straps
Distribute weight across the shoulders and allow precise fit adjustment. Wider straps prevent digging.
Thick Band with Hook Closure
Provides band support like a bra. Hooks are more secure and adjustable than ties, especially in waves.
Tummy Control Panels
Inner mesh or power-net lining smooths the midsection without feeling like shapewear. Subtle but effective.
UV Protection Fabric
UPF 50+ fabric blocks 98% of UV rays. Important for extended sun exposure, especially under water-thinned fabric.
Quick-Dry Material
Nylon-spandex blends that dry fast prevent that heavy, saggy feeling after swimming. Keeps shape throughout the day.

Plus Size Swimwear FAQ
Can plus size women wear bikinis?
Absolutely. Plus size women can and should wear bikinis if they want to. The idea that bikinis are only for certain body types is outdated. Modern plus size bikinis are designed with supportive bra-style tops, tummy-friendly high-waisted bottoms, and fabrics that move with your body. Wear what makes you happy.
What swimwear is most flattering for a plus size body?
The most flattering swimwear depends on your body type and what you want to accentuate. High-waisted bikinis flatter by defining the waist. One-pieces with ruching smooth the midsection. Tankinis offer coverage with the convenience of two pieces. The most flattering suit is always the one you feel most confident in.
What support features should I look for in a plus size bikini top?
Look for underwire or moulded cups, wide adjustable straps, a thick band with back hook closure (not just ties), side boning for containment, and a clasp rather than a pullover style. These features provide the same level of support as a well-made bra, but in swimwear form.
How do I find my size in plus size swimwear?
Our plus size swimwear comes in sizes L to 5XL, with size availability varying by style. Use our size guide to find your size based on bust, waist, and hip measurements.
