Well, the model looks like an ironing board so I hope you have some lovely hourglass curves, OP. But assuming you do, I'm sure you can rock that dress.
I once identified a dress online in a shop in Ho Chi Minh before going on holiday there. I dragged my DH and DS through the city to try the frock on. I'm slim, it fitted, but looked like shit nevertheless. My chest and shoulders were just not right. (I'm not ample bosomed, quite flat, but athletic rather than small-boned). Fantasy punctured. But at least we got to see more of an exciting city!
