This is Addy's Plaid Summer setavailable from 2011- 2016. We have only the dress and the boots, plus the original box and are MISSING the pinafore, socks, and hairband.
American Girl described it as follows:
Addy loves to wear this outfit that Momma made—especially on warm days in Philadelphia! Get her ready for a summer adventure in this outfit that features:
A tan-and-pink plaid cotton dress with a full skirt and ruffled sleeves
A crisp white pinafore with ruffled V-straps, apron skirt and pockets, and ties in the back
Two-tone boots that lace up on the inner side—just like they did in Addy's time
A pretty peach grosgrain ribbon to tie back her hair
