I am 66, around 150 lbs and 5'5",  small on top and more where it shouldn't be.
What I want to say is this is a beautifull dress, the top  streches only as much as needed and the tie holds it up so no oops
the skirt just flows over my middle and makes me feel young.  Will have to wear a wrap when I go out as my arms arn't what they used to be. :)
