You Sexy B*tch! DesignerBeachBods.jpgClockwise from top left: Marc Jacobs, Giorgio Armani, Donatella Versace, Christian Audigier

While this group is known more for the clothes they put ON the runway, it's what they took OFF as they hit various beaches this holiday season that caught our attention.

You can't blame Marc Jacobs for showing off his perfectly ripped bod, and Giorgio Armani - even at age 74 - can still rock a speedo without shame.

Christian Audigier prefers relatively conservative trunks for his time in the sand, while it seems like nothing can keep Donatella Versace from her bikini.

So who do you think wore the least - the best?
