I heard that some of my Asian friends do, so just wondering how other countries are. It seems like a underwear just for swimsuit which are like small knickers that came in skin color and are designed to prevent pubic hair from escaping out the side of the swimsuit/bikini and prevent from transparency of wet swimsuit/bikini showing through the pubic hair. How does this sound in your country ? I heard that some of my Asian friends do, so just wondering how other countries are.

i live in the US and we usually just wear the bikini's by themselves.

No, in America we don't do that. Its called a bikini wax and wearing a suit that has thick enough material so nothing shows through...I've never heard of underwear under a swimming suit.

In America we don't do that we just get a bikini wax

In the UK we don't wear underwear or anything or else it would just get soaking and there's no point anyways because a bikini is like underwear
