Website to Purchase Alvina Valenta BM dresses?

So I've been asked to be in my future sister-in-law's bridal party and we have to get an Alvina Valenta BM dress...super pricey and i'm trying to find online...any suggestions?

TIA

I definitely do not reccommend doing this- sorry... I've been selling dresses for almost 6 years now and I've never seen any good come out of girls trying to buy them online... I've actually heard some pretty bad horror stories- the other problem is that (unless the dress is black) they should all be ordered from the same store (same dye lot) to ensure that the color is exact. Alvina Valenta has some gorgeous dresses but I know they are really pricey- try and cut costs by using a seamstress out of the bridal salon for alterations... (I have the number to an AMAZING one if you need it ) but as far as the dress goes, I would just bite the bullet...
