This post on tumblr started as an example of how you can market clothing to other than a white, stick-thin western couture aesthetic, but this is a great site anyway.
PINUP GIRL CLOTHING - Pinup brings you vintage reproduction clothing and dresses with modern fit and comfort, all designed to play up a woman’s assets and love your curves! Couture for Every Body, our clothing is lovingly crafted in the USA of imported goods.
Okay, this is a great site! You can see your dress on different body types (one that looks like you!) there are many colorways, who can go wrong with classic style? And if you are considering say, a homecoming/prom outfit for your daughter (when she doesn't want to be Iron Man that is) these are far more affordable than something that retails for over $400 and is of questionable taste or wearing again at some point!
