American Girl Halloween: Part One: Kirsten Learns A Lesson. Kirsten was my first American Girl doll given to me in 1989. I loved creating this American Girl doll costume at the old one room schoolhouse.📚 P.S. I’m 5’4” and a S/M wearing a girls size 16 vintage Pleasant Company Kirsten dress I found on eBay!
