Body Glide is the answer.

Yes, and it’s worth the ten bucks.

Swimsuit chafing happens when wet fabric rubs against the same spot for hours—usually along seams, leg holes, or where straps sit. The fix is dead simple: a friction balm stick applied before you put the suit on. Body Glide is the gold standard, but any anti-chafe stick works. It’s not greasy, won’t stain your suit, and holds up through swimming and sweating.

Vaseline works in a pinch but gets messy with sand. Don’t wear a brand new suit to a long beach day either—break it in at home first.

Your thighs will thank you.
