I'm not sure I just ordered asian thongs that were xs and fit like size m....although they looked small....I would love to bid on or auction I'm just not sure how they will fit...:-)
Well, that's your call. I ordered a whole bunch for me and I'm a medium and they were too small which is why I've been listing so many :) When I get out of class I can measure the waist on a couple pairs if you want.
