Throughout The Letter, Leslie Crosbie is seen making some white lace. Leslie’s fondness for making lace is a symbolically perfect hobby for her to have. White is traditionally used to symbolize innocence, but it can also be the color of choice for movie characters who only want to look innocent (Cora in The Postman Always Rings Twice is another good example of a white-wearing femme fatale.) In Leslie’s case, it’s as though she’s trying to create a shroud of innocence for herself. We know she’s guilty, but she keeps on wearing white clothes and working on her white lace. Making lace takes a lot of focus and attention to detail. As carefully as she works on her lace, Leslie has to be equally as careful in crafting her defense.
Most noteworthy, Leslie dresses head-to-toe in white, complete with a white lace shawl, when she goes to purchase the incriminating letter from Mrs. Hammond. She wears white pretty often in The Letter, but ironically, this is the scene where she wears it the most. Leslie is so dedicated to keeping up this facade of innocence that she even wears white when she’s going to see the woman who knows the truth. The sheer amount of audacity it takes to do that is astonishing and I love how Mrs. Hammond has no patience for it. She orders Leslie to take that ridiculous shawl off. As much care Leslie is into building her defense, lace is flimsy and very easy to see through. Other people might be fooled, but Mrs. Hammond sees right through Leslie’s story.
