Christmas Parties, Holiday Cheer, Good Ol' St. Nick, and presents under the tree are just a few things that make Christmas extra special. Get in the mood and help spread the holiday cheer this year as one of Santa's helpers, and Elf, Mrs. Claus, or perhaps even becoming a reindeer or christmas tree! Yep you read that right! We even have christmas tree costumes with all the razzle and dazzle. How about a BIG CHRISTMAS SURPRISE, and YOUR IT! We can dress you as a gift that you can deliver yourself to your loved one. Your imagination is your only limitation at ALTER EGO!
