Stars aren't letting their Halloween costume planning affect their red carpet style.

Colder weather means more long sleeves and longer hemlines, but that doesn't mean celebs are sacrificing style -- or skin -- at all.

Naya Rivera forwent any form of covering up in a slinky black number that left very little to the imagination. The newlywed showed off her hot bod with a low back and hip-high slit.

Other stars like Alessandra Ambrosio, Jessica Chastain and Heather Graham were a little more creative and showed off their gams with the help of sheer or lace overlays.

Blacks and grays are dominating the red carpets, thanks to gloomy weather, but Sienna Miller and Kate Hudson added some color to the mix with bright red ensembles.

Take a look at our favorite sexy stars of the week of 10/26.
