Clothier

The Clothier is an NPC vendor who sells only Vanity items (items that do not provide enhancements to your character, and are for aesthetic value only).

Various clues point to the fact that the Clothier is actually the Old Man who used to guard the Dungeon before Skeletron was defeated. After you defeat Skeletron, you will have freed the Old Man from his curse, wherein he will disappear from the Dungeon entrance and reappear as the Clothier, assuming a suitable vacant house is available. His clothes are no longer tattered, his eyes have turned blue, and he is wearing a red hat.

If the Clothier is killed, he will drop the Red Hat, a Vanity item. Since players can not harm NPCs with weapons, only enemies, Dart Traps or lava can kill him. Note that lava of sufficient depth may also destroy the Hat, though.

Once the Clothier has moved into a house, he will sell the following:

Tips

 * Placing a shallow Lava pit in the floor of the Clothier's house (eg. by pouring one Lava Bucket into an 8 or 9-tile long horizontal recession of one tile height) will cause the Clothier to die and respawn often, leaving behind the Red Hat each time. The Red Hat sells for 2 Silver Coins, so this is one way of making some extra money.
