Shop Women’s Swimsuits and Plus Size Swimwear


Must-have bathing suits combine confidence with fabulous looks.

GBM Sonsie believes that with the right swimsuit, every woman can feel confident and look amazing, and GBM Sonsie swimsuits are the perfect choice for a flattering fit. We’re well known for women’s plus size swimwear, but our suits start at size 8 and smaller sizes will be available soon as well!

Our designs combine practicality with beauty to provide you with the perfect swimsuit. Our one piece suits offer maximum tummy coverage and necklines that range from plunging to hi-cut. Our tankinis offer the same amount of coverage, but come in two pieces and various fits to keep you feeling comfortable and looking great.

GBM Sonsie swimwear features a wide range of colors and patterns. From bright, bold attention grabbers to sweet pastels, straightforward stripes to animal prints, we have something for everyone! Our one piece and two piece plus size swimsuits offer different silhouettes and coverage so you can bare as much as you dare with low-cut necklines and cutouts or choose from more modest suits with mesh and hi-cut necklines. These pieces are limited and new pieces are available every few months, so don’t wait to purchase what you love.

If you prefer the pool to the beach, we’ve got you covered, too. Whether you’re splashing around, swimming, surfing, or laying out in the sun, these swimsuits support all your needs.

While you’re browsing our website, keep an eye out for new collections and new sizes in addition to existing sizes from 8 to custom-made 34W. These plus size bathing suits are must-haves for women everywhere.

We’re dedicated to providing the best women’s swimwear and plus size swimsuits at GBM Sonsie. Let us help you find your dream swimsuit. Fill out our online contact form here or send us an email: help@gbmsonsie.com.
