Don't give them all the same gifts, for anything. Show you love them for the individual people they are, with gifts you choose separately for each one according to his/ her interests or taste. They are only a team or crew to you. That is now how they see themselves, and whether it says bride's crew or they are all alike, people will mostly throw out your gift if one for all, rather than personal.
I had a bridesman in my party so everything i did was either gender neutral or in a version where i could give to him. for instance i gave the girls a necklace/bracelet with a knot design. for him i gave him cufflinks with a knot design.
