    Very good and life saving

    This boron is very nice, fits nicely. It’s period proof, and is versatile so can be matched with many regular tops.

    These are awesome

    I basically am always in a bathing suit and I only wear period panties now so for years I had to find period panties that passed for bathing suit bottoms. These look just like a bikini bottom and they go well with lots of tops I've already worn. They don't swell up exorbitantly in the water when you swim either.
