How to Style Your Swimwear 

Here are a few ideas to inspire you to wear your swimwear beyond the beach or pool. 

  • Our favorite – pair it with a cute pair of cutoffs, sandals, and a boho hat for brunch with the girls or a throw on a chic kimono for a day of adventuring.
  • Some swimsuits are too beautiful to be worn only to the beach. Style your favorite boho-chic maxi skirt with a denim jacket and wear your swimwear as a bodysuit. 
  • Pair a cute bandeau top with your favorite jeans or pants and sneakers. 
  • Ditch your bralette, and reach for your favorite bikini top to wear under a strappy dress or jumpsuit. 
  • Traveling to a tropical destination? Wear your bikini under a linen matching set, so you’re ready for the beach in a moment’s notice. 

Conclusion: Eco-Friendly, Sustainable + Ethical Swim Brands

To extend the life of your ethical and sustainable swimwear, hand wash it after a day at the beach or a dip in the pool. To dry, lay it out or hang dry in the shade.
