I like this over the shoulder look on the doll.
I am not sure if those are sleeping pajamas or at home pajamas. Back then they wore what they called pajamas at home but they were proper to receive visitors in.
I always wanted a riding outfit like this. But I have only ridden a few times. My daughter (now in Heaven) was the horse woman, she loved to ride and did not mind the stable cleaning, just wanted to be around horses.
