Dianna Agron visited the “Late Show with David Letterman” in New York City yesterday.

My first reaction to seeing her in this Stella McCartney Rosalia bonded velvet dress was Black velvet? In August????

A lot of stars have managed to just about get away with wearing Fall 2011 looks on the red carpet, but this is too much for me on a sunny day in Manhattan.

It’s a real shame because Dianna does look really chic in her Stella McCartney dress with a sweetheart bodice and peplum flounce.

This is the first time I’ve seen her without comparing her to her “Glee” character ‘Quinn Fabray.’

I would’ve been in lust with this look had she worn it in October/November.

Just when we thought we’d seen the back of YSL Tribtoo pumps, Dianna returns them to the red carpet much to my (and your) displeasure.

On the plus side I adore her wavy curls and her bright pink lips.
