Roxy.....surf brand.....sizes HELP please!?

ok i accidentally bid on a size 12 roxy top on ebay instead of the ten (i am a size 10/12 and still shrinking so thought it would be best to get the 10) but it is too late and i think i am stuck with the 12. just wondering if roxy brand clothes are generous sizes or quite small? i have never had roxy clothing before, so i am not sure. i know some brands have very small sizes and some have very generous sizes!! if you know the roxy brand well please help me!!!
