The best gift for a 21st birthday is something personal but practical...with a touch of luxe. This period of life is full of milestones - graduating university, moving out of home and maybe going travelling. Think of something that will be really useful for your friend or family member, and group together to give them a great quality version of that item. For example, a suitcase set they'll have for decades to come!
