I'm a size 18 or 20, 5'9", 38DDD chest, hourglass shape, and weigh about 250 lbs (but look like I'm closer to 210-220 lbs). This is a heavy dress--definitely not light or airy. It didn't look bad, but made me look wider than I am. Did not flatter my hourglass. 2X fit fine on me. Maybe it would've looked better with a bra, but the cut doesn't allow for a bra. I returned it because it made me look wide and was so heavy.
