    Costa bottoms.

    Love the coverage! My daughter is 14, looks 16 and isn’t comfortable wearing swimsuits that show a lot. These bottoms have the right amount of coverage for her. Her and I have a lot of junk in the trunk.

    My new favorite swimsuit! I

    My new favorite swimsuit! I was so happy to see that Nani sells size XXS as most swimwear brands do not. I would, however, say that it does run a bit on the larger side because the size was comparable to extra smalls in other brands. For reference, I’m 4’11” and weigh about 100 pounds. I do love the full coverage fit and bright color of these bottoms and plan to purchase another Nani suit soon!

    I tried it on immediately

    I tried it on immediately after it came in the mail (which was super fast). The bottoms fit like a glove and are very flattering. Fits true to size. I love the cut of these as it holds you in while still providing coverage. I can’t wait to wear my new suit on vacation in a couple of weeks!
