Need some advice?

As many of you know my brother and my fabulous cousin Shannon are both getting married in July. Scotty's wedding is July 11th and Shannon's is July 25. I am in both weddings and have already ordered my bridesmaid dresses but have been thinking about what I'm going to wear to rehearsal...I thought for Shannon's wedding I may wear my bridesmaid dress from Scotty's wedding but after seeing this dress from J.Crew...I think I may have changed my mind!
What do you all think? I like both colors
