30 per item.
Upgrading it
Upgrade 
2 through the 
Upgrade Well once the Well reaches 7. Have the supplies below ready and finish construction before using the new level.
Recolouring clothing
Select an owned hat, costume or pair of shoes, choose another colour combination and pay 30. The item keeps its skill bonuses. Rare hats and costumes are not offered for recolouring. All three Dye Shop levels provide the same clothing categories; later upgrades change the exterior.
