Nice just wish there was a bit more to cover in the front. Would be helpful when getting a Brazilian waxing.

Beautifully made & comfortable

I have looked for comfortable, well-made underwear for years. These thongs seem to be made for actual, human women. They fit well, are well made, and beautiful. Buy one in every color
