Leather Dresses F/W 2010

I like Olivia Palermo's long sleeve one, but the one I'm looking at is a cap seeve one, slightly padded shoulders and a v neck by Gestuz. It's nice but I'm worried leather dresses may date.
 
think of them as a black sheath, a blank canvas to build upon. true, the leather makes it more unique, but you can always dress it down with a long cardi, flats, etc. i saw a theory one on sale and was tempted to pick up my second one.
