Why Hasn't She Retired Yet???

Can you imagine how much better Kate Moss would look if she lived a clean and sober lifestyle???

The haggard model tried really hard to look presentable for the Costume Institute Gala at The Metropolitan Museum of Art in NYC on Monday night.

Unfortunately, she still looked a right mess!

Stella McCartney, on the other hand, is a sexy bitch and LOOKED IT.
