Sackgirl

The Sackgirl is the pre-order skin for Sackboy which also can be purchased as DLC.

Origin
It is based on the alternate costumes that can transform Sackboy from a ambiguous/male character to a female character, with additional costume pieces like longer hair, dresses and other feminine articles of clothing. The Sackgirl depicted here features a bonnet with a blonde wig and a paler color of material for her body than the default Sackboy.
