    I need more

    I was really debating purchasing from Negative because of the price point but the black friday sale was too good. I got two pairs and now I don't want to take them off and am going to get more at full price. For those who appreciate high quality underwear, you've found it here. It feels like there's nothing on. I'm normally an xsmall or a small, size 25-26" waist. I bought both pairs in size small and they fit perfect.
