Lyndsey wagoner played in it, she went up into an attic and seen a wedding dress and tried it on. I appreciate it if you can tell me the title thanks.

The actress name is Lindsay Wagner

I'm not sure what movie it was, here's a list of her stuff... maybe a title will look familiar:

Lindsay Wagner (I)

The Two Worlds of Jennie Logan (1979) (TV)

Thank you so much for the title. Appreciate it very much
