Ive been around for a while and now i decided to contribute with something to help all the people who want winter clothes so here I go.
Alliance get the red winterclothes and horde get the green, but why bother watching the neutral auction house to get the opposite factions clothes for skyhigh prices.
This is how you can craft both of them as alliance or a horde.
All goblins are neutral so just charge in your opposite factions city and buy the recipe from the goblin.
Sorry if this have been posted already, I did not find anything when I searched.
EDIT: Also, if you already opend you presents once lets say in Ironforge you can open them a secound time in Orgrimmar and the other way around. Enjoy!
