Christmas costumes

So, I'm back in Madrid and the city's Christmas lights are on, and there's a Christmas market in the Plaza Mayor. Unlike the Christmas market in Prague, this one features absolutely nothing to eat (at this point, anyway; some more stalls that seem like they might be food stalls are just being set up.) The stalls, instead, are divided into three basic categories: first, there are the stalls that sell standard-issue Christmas ornaments (lights, stars). There are also the stalls that sell nativity sets and accessories (like a strange plastic gel to use as water). Finally, and making up more than a third of the stalls, are those that sell masks, wigs, and tambourines. These stalls also feature things such as whoopie cushions.
