I am 135lb 5’5’’. I usually buy small for a together fit to show curves, and it works, But this dress I got a size M and honestly I am not sure I could easily fit into a size XL. It is extremely tight on the hips and after 2 steps it will show my underwear unless I constantly pull it down. Not worth it

The quality of the dress was way more expensive looking than I anticipated. The shape of the dress is not the worse, but not the best. I did feel that it ran slightly smaller than my regular size on the bottom. But that could vary for some depending if you are slimmer on the bottom or more curvy. For reference, I would say I fall right in the middle. I think it is a great buy and would purchase again.
