A glamour prism projects the image of one item onto another. Make sure you have enough glamour prisms before you begin.

Glamour prisms are available on the market board, from Grand Company quartermasters, from vendors, as quest rewards, or when made by crafters who have learned the crafting recipe.

Glamour prism crafting recipes can be obtained from Goberin in western Thanalan (X:12.1 Y:15.0) or Tataroga in Mor Dhona (X:22.1 Y:6.7) after completing the sidequest Absolutely Glamourous.
