Literally some of the most comfortable underwear i have ever purchased. A bit pricey but the quality explains the price point.

Nice quality but the wrong style. I seem to do best with basic cotton bikini. Have wooliest and HZm right now. Looking to style it up a bit to match the negative bras I love, but these are s just to substantial. No need to order up either as they are generously sized.
