ثونغ برازيلي بخيط

The microfibre fabric feels incredibly soft and smooth against my skin, and the slim string sides stay put without digging in. No visible lines at all under my yoga pants.

I forget I'm wearing these, honestly. The string sides are so thin there's zero digging in, and no lines show under leggings. Breathable enough that they don't get clammy on hot days either.

Wore these under a fitted dress all day and there wasn't a single line, which is exactly what I bought them for. The microfibre has a smooth, almost silky feel and the string sides really do sit flat without digging in.
