Weddingbee boards

First off, I was letting both of my out-of-state BMs choose their own dress while I get to pick the color of the dress (abiding to their budget).  I thought this way they wouldnt' be forced to wear a dress they don't like and also it's one less thing for me to worry.  Yesterday, both of my BMs call me (coincidence?) and both told me that I should pick the dress for them!  I don't mind, but I was hoping that they would just do this one thing for me (as they are not helping in other ways with the planning since they are far.) 

So, now I need to find a dress in no time as I am getting married in the very beginning of June.  I need to have the dresses ordered within 2 weeks or so, and I need help finding the dresses in purple.  The dresses that I found in the color I want are so expensive, e.g. Vineyard, Enzoani, Amsale..  Anyone has any idea where to look for jewel toned purple dresses for under $200?  I prefer full-length, but am open to shorter ones. 

I also checked JCrew, AnnTaylor, Nordstrom, but found nothing there.  DB is ruled out b/c one of the BM doesn't like their dresses and it's also quite far from the other BM. 

Lastly, as if I don't have enough BM stuff to deal with, I might have to add another BM to the bridal party, as FMIL told us that my FSIL stated that she felt left out about not being in the wedding party.. 

I am so overwhelmed with what I have to do for the wedding that I am getting a bit panicky..  Eek. Help!

@crebre89: I am going to try Dessy; they seem to have so many colors. I am going to go to store in person to check out the colors..

@barcelona: Thanks for the links, but that shade won't go with what I am looking for. It's too dark and matte.  Thanks, though! :)
