Today I’m wearing a dress with two layers. Depending how many dresses you’ve worn, you might know where this is going next.

The top layer is the main part of the dress, colorful and long-sleeved. The inner layer exists because the top layer is a bit too thin to really stand on its own; the inner layer is black and sleeveless (spaghetti straps). The two layers are attached to each other at the shoulders. They are attached by a chain of thread. Since these are cheap clothes, this is a permanent point of attachment. Unlike nicer clothes, there is no snap to unsnap to separate the layers.

This morning when I was getting dressed, I discovered that the inner layer was inside out and backwards with respect to the outer layer. So I had to figure out what sort of deformation to apply in order to get everything back like it should be.
