My picks:

A new GIRL SCOUT uniform!!!!!!!!

A new camping set with a tent.

A better set of socks and tights.

New shoes in the separates category.

A lifejacket.

Some new oufits that DO NOT have pink or purple.

The Doll carrier backpack/suitcase in more colors.

The doll from the baby and stroller set by itself.

A nice set of basic jeans, a t-shirt, and a hoodie.

More fun socks like the ones from the Ready for Fun outfit.

Stripey tights.

The ability to buy a doll, and choose a different outfit for her to be sent in. i.e. the birthday outfit on a doll being given for a birthday gift.
