Oh, man, I have about ten of those dresses; I am obsessed
with them. I bought the majority off of etsy (from this
seller), but I also picked up two of the Dessy ones on sale somewhere; I just wore one
of the Dessy versions to my birthday party this year, and everyone thought it was the coolest thing.
What to watch out for is how thick the fabric is, because when they're too thin, they get...uh. "Indecent," I guess, is the word I am going for. Another possible word would be "nippy," if you get my meaning. Although, you can
wear a strapless bra, depending on how you tie the dress (and I usually pin the dress to the bra so it stays hidden). For a lot of the styles, though, those little sticky doo-dads work better.
And thus ends my presentation on convertible dresses. Thank you.
