I find a woman's back extremely sexy - the curvature of the spine far more complex and nuanced than the rotundity (or lack thereof) of the barbarian breasts. I love the subversion of an open back. You see someone wearing what might look like a simple sheath dress or simple gown and then once they turn around, they surprise you with a slab of skin.

Vintage, from a la Ladywolf
This trend is popping up everywhere, from vintage dresses to contemporary and designer clothing. It's no wonder since it's pretty flattering on most body types. I'll definitely be watching out for exposed backs at tonight's Golden Globe. Celebrities love to do the show and turn for red carpet cameras.
