Feast of Winter Veil is an event, a temporary Warcraft world holiday that reflects a certain real world holiday. In this case, Christmas. It lasts for 2 weeks over the Christmas holidays.
Tailors on alliance side will find a pattern for the above cute red suit in their mailbox (say hello to Klaudia, my mage). Horde tailors get the green suit, which Dustfire is modeling. There were issues with uneven distribution of the patterns, so if you have a tailor and haven't gotten the pattern, like my Klaudia, you can find the recipes on the Smokeywood Pastures vendors (who appear ONLY during Feast of Winter Veil) in Orgrimmar and Ironforge. Not sure if they'll do it the same way next year, but Smokeywood Pastures is neutral and therefore horde and alliance can fight their way to buy the opposing outfit recipe.
Leatherworkers will find a pattern for Winter Boots in their mailbox. Though a leatherworking recipe, the boots are cloth and wearable by anyone. (Dustfire is also modeling these boots.)
Outfits and boots have no bindings, so you can trade, loan, borrow, and sell these outfits to your heart's content.
There are issues with the suit looking "skanky" on girls. In the middle of taking the picture to your right, I had to /ignore a guy for making suggestive comments.
My stance on the clothes is thus: I found them in WoW Model Viewer and made that Christmas Klaudia image a few months back, then searched to see if they were available in-game. From what I could tell, they weren't, and I was a little disappointed. So I was very excited to see that now they are, because they're something I specifically wanted.
I just have to hide from boys while I'm wearing them. O.o
Green and red Santa hats have a chance to drop from any boss in the game during these two weeks. These hats are bind-on-pickup, so you have to be there to get it.
/kiss a holiday reveler in any inn, and they'll give you something fun like snowflakes to shower on another player or a +20% spirit increase item that you can only use on another player.
Winter Veil Disguise Kit: Turns you into a snowman. Requires a snowball to use. Supposedly shows up in the mailbox, but I don't know anyone who's gotten one, though I've seen it.
Gather your quests in the hubs of Ironforge and Orgrimmar.
- Treats for Great-father Winter: (Goal: 1 milk & 5 gingerbread cookies.) Get 5 [Small Eggs] and buy milk from a food & drink vendor. Get 5 [Holiday Spices] from a special holiday goblin vendor. If you're a cook, get the gingerbread recipe from that same vendor, or ask someone else to make it for you. Turn in.
- Reason for the Season [A/H]: (Goal: Talk to someone.) You'll be sent to talk to some famous leader after the first part. Easy.
- Stolen Winter Veil Treats: Go to the snowman at 35, 72 Alterac Mountains. You'll then get You're a Mean One, where you have to kill the level 36 Abominable Greench. Watch out for higher level horde and alliance if you're on a PVP server!
- Metzen the Reindeer [A/H]: Levels 45+. Best done as a group quest. Rewards the non-soulbound [Preserved Holly], allowing you to transform your current mount into a reindeer 5 times, lasting until you dismount. Flying mounts give you a flying reindeer, which leaves a trail of sparkles when you fly. ^_^
All found in [Gaily Wrapped Present], which are available for pickup under the trees in Ironforge and Orgrimmar on and after December 25th.
- Snowman Kit: Will /wave and /dance back at you, but does not follow you.
- Green Helper Box: Male gnome in green Christmas outfit.
- Red Helper Box: Female gnome in red Christmas outfit.
- Jingling Bell: Small holiday reindeer pet.
Gifts under the trees in Orgrimmar and Ironforge are available starting December 25th to the end of the Winter Veil holiday. Each type of gift is marked with a quest-giver's exclamation point (!) and can only be picked up once. Pet items can be traded, bought, or sold if you didn't get the one you want.
