The scarlet Sprite, of January 2009.
The reason i like it so much is because it doesn't have just one big item that takes up 90% of the avatar, meaning that anyone else wearing that item will look exactly like you. Instead it has lots of smaller things, that you can use to mix and match make an unique avatar. Furthermore, though the items themselves look elegant and pretty, when mixed with other Gaian items they can become something a fierce protective person would wear, something a beautiful elegant person would wear, something a cute avatar would wear, or even something a sinister avatar would wear. Though I am not 100% sure about this, I also believe that it is unisex. Last time I checked, not every item on Gaia is unisex, and this tends to drive people batty. If you have any more reason to doubt why I love 2009's Scarlet Sprite above the other January monthly items, answer me this: what's NOT to love about it?
