My first response is that you clearly have not searched everywhere since if you had you would have located it. I too find it much easier to have somebody else do all the work for me.
Perhaps if you go to the original article you linked to you might just find the reference for the picture and thus who made it and onward to where you can get it.
If you want people to help you need to be a lot more specific as to what you are looking for. Is it the blue or the puffy bottom you like? How about strapless? What exactly are you looking for? That particular dress?
If so that particular dress is in the range of $4,000! Do you really want it of something cheap that is somewhat like it?
Here it is for $208. I'd buy that immediately. send me a message with your email address and I'll send a link for the dress to you. I am not ranked high enough to send you a message or to post a link. Pretty f-n lame!
Oh wow that looks like a custom made dress. You might have to get a dress that sort of looks like that one and tailor it to look exactly like it. The only other way I can think of getting it is searching boutiques online or trying to research the link to find out where it came from.
Wow, that's really nice! I work at a dress shop. We sell poofy dresses like that, so I bet you could find something similar. The color may be tricky though. Check around in stores near you. Good luck! :)
