A Letter for Evie (1946)

Evie's co-workers at the uniform shirt factory, and her almost-fiancée's inability to kiss, inspire her to slip a letter into a size sixteen-and-a-half shirt for some anonymous soldier. It's received by "Wolf" Larson, who immediately throws it away, but his sensitive, dreaming--and short--buddy John McPherson snags it, and begins a correspondence with Evie, pretending to be Wolf. But things get complicated when Evie wants to meet her tall, handsome soldier. And even more complicated when Wolf sees Evie and likes what he sees.
