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).

The Clothier is the same character as 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. Once a suitable vacant house is available, he will spawn and sell items. 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, another Vanity item. Since players can not harm NPCs with weapons, only enemies, Dart Traps, Boulders or lava can kill him. Note that lava of sufficient depth may also destroy the Hat, though.

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

Names
The clothier may have any of the following names: Sebastian, Rupert, Clive, Nigel, Mervyn, Cedric, Pip, Cyril, Fitz, Lloyd, Arthur, Rodney, Graham, Edward, Alfred, Edmund, Henry, Herald, Roland, Lincoln, Edgar, Eustace, and Rodrick.

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, which can be sold for each (or worn).

Trivia

 * Most of the Clothier's dialogues refer to movies starring Tom Hanks. The movies are "Cast Away", "Forrest Gump" (IMDb links), 'Ladykillers', 'Apollo 13'.
 * All of his purchasable items require a few gold to be bought, unlike many others.
 * He is the only one of the NPCs to drop an item upon death.
