Activity for Alyssa

I haven't been on here in a few days, so forgive me if there is already a thread, but I scrolled through a few pages and didn't see one. I had some doubts about my wedding dress mainly because I have VERY broad shoulders but I walked into a David's...

I want to ask each of my bridesmaids with a fun and cute way to be in my wedding...however I have no idea what to do or where to look. Any ideas - websites, DIY, or what you did?
