Activity for Rebekah

So we had to postpone on April 18th wedding, and the new date is in July. Our colors are purples, silver and dark green. Very spring. But now I'm worried that dark green isn't summery enough, and now I'm not sure what to do. What colors should I use...

I want to get my bridesmaid a robe that has their initial on them. Wheres the best place to get them at the best price and quality?
