Just a friendly tip that may help someone out... when my MOH was getting married in 2016, she was not able to visualize ANYTHING. She didn't know what dresses to pick for her BMs or what kinds of clothes the GMs should wear that wouldn't clash, etc. I told her to download a collage app for her laptop and iPhone so that when she was on Pinterest, or any website, she could just screen cap what she liked and put everything in a collage next to each other to see how it looked next to each other. I did the same thing for the DIY items and random decor items we purchased for the wedding - I took photos and then in an app, I placed them into the venue to see how they'd look. It really helped her out.
I just created the below collage for my bridal party to see and thought I might leave that tip for someone else who is having the same issue.
