This is my pattern, from 1946. I made the short sleeve shirt, with a collar and the long pants.
Fabric: Flannel with tiny bears
Notions: 5 buttons and more white thread
Cost: about $20
I'm happy with them! We also took the wiener dog to the dog beach and got him to swim. LOLZ! So hilarious! He would only swim from the sandbar towards the shore and he did not look happy. I'll have to make a video at some point!
