Gift help!

I’m getting married and need help/ideas for what to get my bridesmaids as a gift. I’m definitely getting them all robes for getting ready and was originally gonna get them a bunch of brides maids stuff like brackets and cups but decided not to because they will only use it once and I want to get them something they will actually enjoy. My limit is about $50 per girl since I don’t have a lot of money. Thanks!
