Ok ladies I'm in a bind... Went out shopping this weekend and fell.in.love with Sophia Tolli's "Emilie". I felt like she was made for me...a rarity in this entire search process! No pictures of me in the dress since the shop had a strict no camera policy; but here's a few shots to give you a better idea:

Only problem? I cannot, in good conscious, spend the amount of money on a dress that the shop was asking for her. So I turn to the hive for some help...I'm not so "up" on what's out there--been more or less feeling my way through the entire process. Do any of you know of any designers or specific dresses that have a similar look? Specifically, I'm looking for:

-Corset back

-A-line

-Rouching/side gathers

-Sweetheart neckline (or one that can easily be made into one)

-Strapless

-Chapel train

-Some beadwork on the bust/back/abs area (but not down onto the train/skirt if I can help it)

As if that wasn't tough enough--I'm a non-standard size, so I'm looking for lines that do extended size runs, too. (It's cool if there's a upcharge for that sort of thing, but hopefully not too much of one.) I'd like to try to avoid any overseas/online retailers just to avoid the drama; pretty much anything that can be purchased in the Mid Atlantic / New England area is fair game.

Thanks in advance for the help and advice! :-)

PS-The date in my profile is incorrect (on purpose) for privacy/secrecy reasons. I will have more than enough time to make the purchse, so no worries there. B-)

How about the Gwenyth by Maggie Sottero?  I just ordered mine last week!  It has beading on the chest, sweetheart neck line, rouching, side gather on left side, corset back, AND A-line. 

Keep in mind you can't tell what it looks like the best (especially the back) because the sample dress I have on is too big....
