I ordered a size 6 in white and I'm 5'2" and 127lbs. You can see from the photo it's a good fit and wears comfortably. I was a little worried that with my height it would drag too much but you can see (I"m wearing flats) that it's not too bad.
The dress came with the cute little belt and I picked up some $4 trader joe's flowers and it was amazing!
