These past two days I have been busy sewing a summer wardrobe for the American Girl doll (or other 18 inch dolls). I made some for my granddaughters and made some to be listed in my Etsy store.
My two favorite patterns are from two different doll designers Bunny Bear and Love U Bunches.
The shirt's were made from a modified pattern from called Bunny Bear - Bella Twilight jeans and top. https://www.etsy.com/listing/40649869/bella-twilight-jeans-and-button-down?ref=shop_home_active_2
The shoes are made from Love U Bunches Plain Jane Flats. I slightly modified my using a 5mm foam instead of 2mm.
If you love to sew like I do - then you will love both of these patterns.
