"Would have been perfect, sized WAY TOO BIG"
Order AT LEAST one size down. In my case I ordered an XS (my normal size), so no other option for me. The armpits/chest would have been ok, but there was a ton of room in the hips/stomach - I could have zipped 4 gerbils in there with me! Nice and lightweight, the stitching gives it enough flare to be a little different, would have packed down very nicely, but alas it's too big.
