I am usually a size 8 so ordered a size bigger as most say they are a snug fit. It would have fitted me okay but the overall size was a bit strange. Everything from my bust upwards was a tad larger, as i expected & would have been okay, but everything lower was alot snugger. The sleeves go from being large at the top to being tighter from the elbow downwards! Same with the body, tighter from below the bust. So a very odd and annoying fit really. Will be okay for an extra layer but that's it really.
