Jaime Lannister

What to wear: A leather coat with a red shirt underneath and a slick new haircut. Carry a sword, and paint one of your hands gold.

Bran

What to wear: A big fur and a long wig. You need a friend to dress as Hodor, so he can give you a piggyback ride.

Margaery Tyrell

What to wear: A beautiful blue gown with your hair done up beautifully.

Ramsay Bolton

What to wear: A long-sleeved shirt with a brown leather vest over it.

Joffrey

What to wear: Joffrey needs a long, ostentatious coat, a sword or a bow, and a golden crown that looks like antlers. If you want to be Choking Joffrey, start clutching your throat and a goblet.

Meera Reed

What to wear: Furs, furs, furs! (Faux, of course.) You're used to the cold, so you'll need to bundle up big time.

Ygritte

What to wear: Lots of furs from head-to-toe, plus leather gloves and a bow and arrow. Wear a red wig with half of it pulled back.

Ellaria Sand

What to wear: A fierce black cape with shoulder pads over a black slip dress, with a brown belt crisscrossed over it. Lots of black smoky eyeliner.

What to wear: A long hooded gray robe with a rope belt. Bring extra face masks so you can change faces periodically.

Lyanna Mormont

What to wear: Like most everyone else, you're going to want to stock up on some dark clothing and furs. Lyanna has a recognizable hairstyle too, so practice parting your hair down the middle like that.

Yara Greyjoy

What to wear: Break out your typical body armor. You're from the Iron Isles, so you're a little less flashy than the Starks or Lannisters, but you still have pride.

Leaf

What to wear: This one will require a bit more work. You'll need a heavy, dark dress, an elaborate updo, and face paint to cover your upper body in crazy, tree-like veins. Creepy contact lenses are a must.

Melisandre, Old AF Edition

What to wear: Well, there's not much to this costume, so that's a plus. The true, old version of Melisandre is butt naked, so get yourself a body suit that matches your skin tone and a stringy white wig. If you can use makeup to draw on a few wrinkles, you'll nail it.

The Shame Nun

What to wear: You can buy a gray nun's costume [7], or just throw on a long-sleeved gray dress and wrap a gray scarf around your head in the same way she does. To add the finishing touches, wrap a light-colored rope around your waist and carry around a thick book and a bell.

Lyanna Stark

What to wear: Lightweight quilted armor, complete with a skirt and gloves.

The Waif

What to wear: A short blond wig and some variation of gray pieces of clothing layered over each other. Feel free to carry a long wooden staff or fake dagger around with you in case you come across anyone dressed as Arya.

Lancel Lannister

What to wear: Head-to-toe robes with the Faith of the Seven's symbol carved into your head. (Just kidding, use makeup.)

Thoros of Myr

What to wear: Brown, dirty clothes. You'll need to start growing out your scruff now, and your hair will need to be long enough to tie into a high bun.

Brynden Tully aka The Blackfish

What to wear: You'll need some pretty sophisticated armor to pull this off. Don't forget your chain-mail underneath; you get into a lot of battles. Add some salt-n-pepper hair and you're there.

Wun-Wun

What to wear: Lots of old, dirty fur, shoddily tied together. Dust some fake snow on to get that lived-in look. You could get prosthetics for your face, or you could just tie your hair back.

Beric Dondarrion

What to wear: Dark robes, cape, and armor with some cloth tied around your eye. Seriously, you could just use a headband.

Tormund Giantsbane

What to wear: Lots of furs, plus a sword, and a wild beard and untamed hair.

The Mountain (Zombie Edition)

What to wear: Unless the person reading this is Shaq, we're going to go ahead and assume you're not nine feet tall, so don't worry about your size. This costume is a little tough, though, considering the undead Gregor Clegane rocks a full suit of golden armor. You can always wear a gold, long-sleeved shirt and pants, and then just buy a helmet if you want to keep things simple. Just make sure you make any visible skin look like the gray, rotting flesh of a corpse.

The High Sparrow

What to wear: Honestly, you could just cut holes in the side of a large potato sack for your arms, and you'd have something akin to the High Sparrow's raggedy dress. If you don't have a potato sack lying around (understandable), just throw on your baggiest, drabbest, light-colored clothes, and get yourself a white wig. Go barefoot if possible, and feel free to carry a book around with the Faith of the Seven's seven-pointed star carved into it (or better yet, ask your friend to wear a black robe and paint the symbol on their forehead, and follow you around all night).

Olly

What to wear: Rock a short brown wig with a black turtleneck, a black coat, a leather belt (or some kind of fabric to tie around your waist), black pants, and boots. Don't forget Olly's favorite accessories, either: a knife and a SNEERING, BACKSTABBING GRIN.

Tommen

What to wear: A short blond wig with a suit buttoned up to your chin — you'll probably have to invest in one from a Halloween [8] store. Complete the look with a crown.

Rickon Stark

What to wear: Very raggedy furs and other various warm layers. Rickon's been out on the run for a long time, so make sure to get that moppy hair and add dirt to your face.

Benjen "Cold Hands" Stark

What to wear: A cozy black fur ensemble with your hair or wig pulled halfway back. Wear some bluish face makeup to look semidead and very cold.

Ned Stark

What to wear: Much like the other Stark men, Ned wears heavy-duty armor and fur and wields a magnificent sword. Set him apart with the long, half-up hairdo.
