The window displays around Union Square are all a flutter with fancy tutus and pretty pink pointe shoes, circling buzz for the SF Ballet's 2011 Season, opening with Giselle this Saturday evening. 

The ballet is a classic place to see and be seen in SF. With that in mind, we're channeling our inner Gisele, and thinking long, lean and elegant.

For the perfect night at the ballet, remember that simple can be devastatingly beautiful. Look and feel as graceful as any prima ballerina in this classic one shoulder champagne gown. If you're hesitant to wear a floor-length frocks, don't you fret -- a belted higher waist will lengthen your legs, while adding  shape. Get even more leggy with a pair of strappy black pumps, featuring a small platform for comfort. And finally, add a little Black Swanedge to all that elegance with a textured satin clutch and silver studs.
