While the silhouetted nudes are a famous pre-code scene, my favorite is with Joan Blondell later on. She is getting ready in the bathroom and talking to a friend while doing her hair. The outfit is skimpy (especially for the 1930s!), but there is a hint a areola slip near the end of the scene.

Also included are still from the more famous dance number.

This must be one of the first teasing scenes. While there was nudity in cinema in the 20s and prior, this must be one of the first slips!
