ELI5: Why is it so much harder to put on clothes when your skin is wet?

Clothes are much harder to put on when your skin is wet because water acts like a temporary glue that makes the fabric stick to your body instead of sliding over it.

When your skin is completely dry, fabric touches your body loosely, letting your clothes glide right on. But when you are wet after a bath or a swim, a few invisible forces make getting dressed a big struggle:

• Water likes to stick together: Water has a superpower called surface tension. Tiny drops of water love to hold hands with each other. When water gets trapped between your skin and your shirt, it grabs onto both at the same time, pulling them together like suction cups.
• Fabric absorbs water: Your clothes act like little sponges. As soon as dry cloth touches your wet arm or leg, it soaks up that moisture. The fabric becomes heavier, swells up, and loses its smooth shape, which makes it bunch up into tight rolls.
• More friction is created: Instead of sliding smoothly, the wet fabric rubs hard against your skin. In science, this resistance is called friction. It is the same reason a wet suction cup sticks tightly to a window while a dry one falls right off.

That is why pulling a pair of tight jeans or a fitted t-shirt over damp skin feels like trying to pull an angry octopus onto your body. Toweling off until you are completely dry removes that watery glue, so your clothes can slide on easily again.
