Last year DD was about 1.5 and DS was 4. He wanted to be a farmer, and conveniently we had an adorable hand me down chicken costume in DD's size from a family friend. DS wore Carhartt overalls, a straw hat, plaid shirt, bandana, etc. DD wore the chicken suit. DS has a ride on tractor and we have a small wagon that hooks to it. DS pulled DD around the neighborhood. She rode in the wagon dressed as a chicken, and we had a bunch of straw in there and a little blanket for her to sit on. So not terribly complicated or over the top cute, but all together it was pretty adorable
