I bought some of these in different prints and colours, and am sadly disappointed with them. This particular pattern is 60% cotton, 40% polyester, except for the gusset which they say is 100% cotton. As I said in a review of one of the ti voglio 100% cotton hipster underwear, despite my measuring myself against the fit chart they fit like large briefs. I'm sure many people would find them comfortable, but I'm not at all thrilled. Bring back the old bikini fit, and ensure that cotton = cotton.
