Size down, but how far down? tricky sizing.
My store had only one of these, in a size xs (i tend to be more of a s in most retailer items). it was roomy. i am 5'2, 34d, & figured a petite small would be a perfect fit. i ordered the ps, it arrived today, & is still pretty big! the sleeves (which are quite flared) are a little shorter, as is the overall length, than the regular xs, but overall the ps feels just as big, if not bigger, than the regular xs! trying to decide if i should go back for the regular xs or order the regular xxs.
