Dressing the part

As a writer, I tend to live in jeans, sneakers, t-shirts, and vintage beaded sweaters. I do own some nice things, mostly from years ago when I had to dress coherently for my job as a writer for a video club (Bruce is back and better than ever in this high-octane thriller!) but I tend to save those for weddings or parties or....readings.
I'm thrilled that I'm going to be at BEA signing books for Pictures of You and that I will also be giving a talk, but that means....I need something to wear...
