Kathryn Grant.
I was watching this old movie, on you tube. She had that 50's "Nice girl", look. I checked the bio., and looked up Kathryn Grant. She married Bing Crosby, the same year, as this movie, and became Kathryn Crosby. He was 30 years older then Kathryn. You can see additional photos of Kathryn: go to google images, and type in her name.
