Asos and ModCloth both have awesome plus size options.

They have an option for you to do custom measurements, different sleeve types, different necklines and different hems/length. They go up to a size 6x/36W.

Pretty much any dress you like on the site can be made to accommodate your style and they have a wide selection and the price is reasonable!

Torrid is great. And it totally doesn't have to be white. I wore a cute floral dress for my shower.

Kiyonna.com has a lot of lovely dresses (I actually got my wedding dress from there!). Dressbarn is also a good option and I even have a few cute dresses with oldnavy.com-they have a lot of plus sized stuff online. I don't do sleeveless so I've acquired a few dressy cardigans/shrugs to wear with all the sleeveless stuff (again, mostly from Dressbarn)

@Sidoine, we ordered the bridesmaids dresses from that site! They came out really well and I would totally recommend the site. Might be cutting it close for April tho. I am a 16 and have had really good luck at Ross and Nordstrom rack. Ralph Lauren and Calvin Klein on the cheap.

I really like ashleystewart.com and found a few really cute white dresses there. I bought one that is lacy with sleeves that I think I'll wear for my bridal shower. I also second Eloquii, they usually have some nice options
