Speaking of revealing, I was googling for "peacock dress", because I had idly remembered that I wanted to find one of those flapper peacock dresses. Instead, I found this body-paint "dress." Probably not safe for work.
Anyway, please turn your attention back to the polka-dot dress. It's completely not appropriate for the rainy cold weather we're having here now, so all the more reason to consider it, at length, now, and bookmark it for next summer.
One thing — the nice folks at mignonette in Brooklyn are very proud of their dress fitting ALL THE WAY UP to a size 12/B34! Sigh. Because we all know there's NO ONE in Brooklyn who is bigger than THAT. Ah, well, if you really like it, write them and see if they'll grade their patterns up to at least a size 16, preferably to 18 or larger, because this is a style that's really great on bigger gals.
