The outfit on the top is from the American Girl Place in Chicago. It's in the souvenir section of the store. I added some flats from a different doll clothing company, because the silver of the shoes goes with the star on the shirt.
The outfit on the bottom is something I made myself (kind of). The pants are from the Sporty Winter Outfit ($34) and the same shoes from the Chicago American Girl Place outfit. However, the shirt is actually from Build-a-Bear. The outfit should have a belt, but I couldn't find one, so...
Last, but not least, we have Chrissa's dress. She was Girl of the Year in 2009.
Have fun this summer! I'll be posting a summer party tutorial soon.
P.S. Sorry about the poor picture quality. I need to get some sort of lighting.
