You shoulda gotten your ugly sweater back in 2009 after the Sweater collapse. Now demand is higher than ever, and ugly Xmas sweater prices have more than tripled. In fact, 2014 projects to be an even better year for sweater commodities.
make one. get an old sweater and get to work on it like some kid at a sweatshop in costa rica. it's fun.
The Value Village on Shepherd has carts full of them. Otherwise there are more expensive retail shops that have them
I just noticed that you had replied to this. I went to the Value Village yesterday and they had a cart of them. I don't know if your Christmas party has already passed, but I've also seen them at Sand Dollar and those weird shops on Westheimer and Dunlavy.
