I am in a similar dilemma. I saw a great bridesmaid dress quite a while ago and haven't been able to find it since. It was very simple. White on the top and a black skirt. The only thing that distinguished it was a black satin ribbon around the top at the natural waist that was NOT a bow but rather a simple criss cross. Any one have ideas?
I know one good site: JenJenHouse.com. I recently bought one dress from them.
It arrived on time as promised and seriously is amazing! I paid 100.00 for this dress and it looks like I paid 500 for it! So pleased with this purchase!
Also, recently they have an activity on their FB. You could go and have a look. https://www.facebook.com/events/141111119389779/
