Vintage Sears Bicycle...need to know the production year.?

I purchased this vintage bicycle at a garage sale yesterday. It looks like it could range from the 50's to possibly the 70's. It's a female bicycle, bright blue frame and chrome fenders. It has a Sears circular medallion on the front of the frame, and another that banners around the seat pole of the frame. It also has white pin striping, and white, painted , star decals. Can anyone give me some history on this find? Thanks in advance!
