I saw these recommended on here months ago, have had them bookmarked for ages. Am about to buy...but am completely thrown by their sizing! I usually wear a 10, might go to a 12 for extra comfort as these will be monging trousers. So I was debating S or M, until I went to their sizing chart, here. According to which (I got a tape measure out and everything) I should be in a 16-18! Has anybody bought from here who can give me some advice on whether their sizes are really ridiculously small, or whether I shouldn't take any notice and go for a M as usual? Thanks ever so.
