I think I've started something here
I like the not being the biggest in the room thing. Quite a few of my friends are quite big, I ordered exactly the same top - same size, everything, as one of them mail order. When it arrived I was amazed how much baggier it was on me, as I never realised I'd got thinner than she was. Not in a competitive, mean sort of way, but it's great to be thinner than someone!
