The Wardrobe
Every piece you equip unlocks its look for your account. In town, open the Wardrobe (U) to change your look per slot, hide a piece, recolour your armour, pick a character effect or wear a costume; stats never change. For now everything is unlocked for everyone, free.
Costumes
A costume replaces your whole look while your weapon stays in hand. Each has six dye parts (main cloth, second cloth, trim, leather and straps, metal and plate, gems and runes), 44 colours with metals and shades, and you can save colourways.

The Green Knight
A full suit of old plate under a torn white tabard, the helm horned.

The Ranger
A hooded woodland ranger in dark leathers and a green mantle.

The Witch
A ragged witch's robe hung with bones and charms, under a great crooked hat.

The Bare Bones
Nothing left but old bones and a few scraps.

The Hooded Rogue
A hooded, masked rogue in dark leather.

The Gladiator
Bare-chested under a spiked pauldron, a red half-cape and greaves.

The Candle Saint
Thorn-crowned and bandaged, in blackened plate and red cloth: a saint of the Long Quiet who keeps the last candles lit.

The Dawn Saint
White cloth, gilded plate and a halo of brass candles: the saint as the shrines paint her, before the Quiet came.

The Star Witch
Night-violet robes stitched with silver stars, and a hat wide enough to keep the rain off a whole party.

The Dragon Knight
Blood-red dragonscale plate, horned helm and clawed gauntlets: a knight who wears what he slew.
