Sally has been blogging and consulting for quite awhile and seems to genuinely enjoy helping women grow their personal style. Dress to express (yourself) not to impress, it'll help her see the real you more quickly.

And remember.... have fun with fashion!

I'm not sure what I'd wear, but I'd definitely bring something along you wanted some help styling (a wardrobe orphan you want some work on), and perhaps a couple pictures of "inspiration" to give her an idea of where you want to go.

Have fun and tell us how it goes!
