1. (N.) A Christmas outfit is the result of having recieved many clothing items around the same period of time. Naturally, someone would want to wear all the gifts they've recieved at once, and when they do, it creates a mismatched catastrophy.

2. A outfit consisting of purely new items of clothing.
Ex. "Ew, she's wearing egg socks, a flannel, a sweater, shorts and reindeer print leggings all at once! Must be a Christmas outfit..."
