This dress is a vintage 20s drop hem style, not meant to be tight to form.  that said, the bottom is loose so may want to size down.  5'2, 145 lbs= s.  i bought the neutral- navy pattern and it is absolutely gorgeus!  hints of peach and beautiful lace detail.  i literally got compliments all day long- from friends and strangers.  i paired it with a dark denim jacket.  absolute must have for sale price.
