Activity for Gabe's Babe

Is it a bad idea for my MOH to have the same dress as the Bridesmaid but a different color. Example BM dresses are sunshine yellow with cobalt blue sash and MOH cobalt blue with a yellow sash?

I know that in my previous post I said that we chose the colors but I was looking at things on the IB and decided red is so cliche...so we went with drum roll please.....cobalt blue, yellow, and gray!!!! Now what's next?

I have no idea where to start planning this wedding. It isn't for a year and a half, but I know me and I won't be able to decide on anything. I have chosen a venue and colors. The problem is everyday something changes. I need help badly!!!
