Feel fabulous in fringed suits or ribbed ensembles that add dimension and design to your look. Feeling flirty? Try a plus size swimdress for some cute mermaid vibes.

Try Trendy Plus Size Swimsuits

The one-piece is a classic look that stands the test of time. And, with Dia & Co, a sexy, plus-size one-piece swimsuit is just a click away. Add personality to your swimsuit collection with creative cutouts (look for monokinis with adventurous designs) and interesting necklines. Some of our favorite trendy plus size bathing suits feature a v-neckline and offer a higher cut to show off a little in the back. This one-piece by Andie Swim is a great example of classic done sexy. 

Play with Color and Swim Accessories

If you’re looking for a black one-piece swimsuit in extended sizes, Dia & Co has got you covered. Just like your favorite little black dress, no closet is complete without a little black swimsuit. But why not grab a second suit for when you want to wear something vibrant?  In our one-piece swimsuit collection, you’ll find swimsuits in a variety of styles and shapes—even super cute and colorful two-piece swimsuits. If you want to get a little adventurous but want to keep it sleek and simple, try a cute cutout or color block accent to start. Feeling like you want to go bold? Try a criss-cross bodice or a deep v-neckline. And for when you need a stylish layer, our cover-ups and kimonos make the perfect swim accessory. Truth is, at Dia & Co, you’re bound to find all the plus size swimsuits and beach accessories you need to hit the boardwalk, hang on the beach, or chill poolside in flawless style.
