There are plenty of cute swimsuit cover-ups out there, but my tried and true favorite is a Ralph Lauren men's OCBD (oxford cloth button down).
I either take my dad's hand-me-downs or buy new... although the hand-me-downs are the best because they are the perfect kind of worn-in. It beats other cover-ups because it can be thrown in the wash a million times and doesn't need to be ironed. It always looks classic and put together and is easy peasy to throw on (similar to the side braid). This was a vacation staple for my cousin, tBh and I.
Do you rock the men's OCBD as a swimsuit cover-up? Have a fabulous day!
