I went off the sizing chart and used bust size to determine size. If it just said the size 16/18 is an XL, 12/14 L etc. then I could have picked the right size. Or perhaps I should go off waist size?? I still loved it. It's a light feeling material with a little stretch to it. Very cute style with the 3/4" sleeves. I want it in my size but it's n/a in the pink. If I wasn't floating in it, I would keep it even a little big I liked it so much. But it's too big so I have to send it back. :(
