'Dancing' with Recycled Dresses

New season, new contestants, same old outfit.

Swimmer Natalie Coughlin was given the same frilly blue dress for her web promo that gymnast Shawn Johnson wore on the show last year -- giving the lovely ladies something else in common other than the 2008 Olympics.

The dress could turn out to be good or bad luck: Johnson won "Dancing" last year ... but she also gained an alleged stalker.
