JennL, a friend of Xyra's, recommended a great place to build your wardrobe.
It's not official AG wear, but quality outfits and accessories to fit 18" dolls. So if you have Springfield, Our Generation, AG, or any of the other 18" dolls you might want to check out Harmony Club Dolls.
One of the great things is that they have FAIRY costumes! I love the pink butterfly fairy.
Also, they have giveaways through their Facebook page. Ask mom to help you with that.
Have fun window shopping!
