Calvin Klein briefs for sure. I own the microfiber steel, microfiber cotton X, micromodal, ck one, 365, cotton-stretch and the classic low-rise briefs, in order of my favorites. The microfiber steel feel and look so amazing. I recently bought Evolve bikini briefs at Target (2 for 12) and they look and feel amazing. Supposedly Evolove is 2(x)ist's brand for Target stores. Check them out! I'll post pics soon!
