I have to make a quick decision and don't have time to ask the 12 and 14 year old nieces what they would prefer - they are helping with programs, etc...so I am getting them corsages. All of the other corsages are pinned (with a magnet), but the florist initally thought a wristlet would work well for them. Is this because of their age? Would you guys get them a wristlet or a pinned one so they match mom's and grandma's? Thanks!
