My wedding colors are black, white, and red. My BMs are wearing black dresses with a white sash around the waist. They will be carrying red and white rose bouquets. One of my BMs mentioned last week that she'll probably be freezing in a strapless dress and might like some coverage. So I was thinking that for one of the BM gifts, I could buy them all a cute red shrug or crop cardigan to wear with their dresses, then they can wear it again later. I'm just concerned about how a cotton cardigan will look next to a satin dress. So what do you think?

This is the dress.

This is the type of shrug I'm looking into.
