I have decided that even though the market is in bad shape, I hate my current job enough to look for a new one. It's going to be really difficult but I'm always up for a challenge, and I would like to give myself every advantage, including wardrobe.

I think I'm pretty well-stocked with interview outfits. I have 2 pants (one black and one black with white and subtle purple pinstripes), 3 skirts (brownish-grayish pleated skirt, brown tweed pencil skirt, and black pencil skirt), and a lot of shirts that would work fine with any of the aforementioned bottoms. What I'm missing is some sort of top layer. A lot of my shirts are not appropriate on their own, but would look fantastic with a jacket. I just don't want to look too conservative and "suity"--I know that sounds odd since a suit is generally considered the best and most safe thing to wear to an interview, but it's not really the sort of thing that makes an appearance in my field. I was actually discouraged from it by my career counselor.

Given what pieces I already have, what colors/styles should I look for? Keep in mind that I am in a creative field and creative details (but not wacky, distasteful, or loud) can be a good thing.

Any ideas or suggestions (particularly about color)?
