That's a great way for Dagwood to hide in plain sight! I knew that the strip had used the dress gag before, but didn't know about the movie version. Another for the queue!
I remember Dagwoods position well. Both my Grand mothers were sewers, she made half by her income from dressmaking, loved the numerous 1890s costumes she made for several women in the mid 1960s for several years, they were great to be a dressform for!Sara Blevins
