Every year since 2013, American Girl has released a store-exclusive holiday dress in November. It's always super fancy, and super expensive. Last year's dress, the Ruby Ball Gown Set, cost a whopping $72! But 21 weeks ago, @agupdatenews found a fancy purple ball gown. Turns out, with a shawl, white sandals and a headband, it's the store-exclusive holiday dress! @agupdatenews has pictures of the gown and shoes, but no shawl and headband as of today.
