The accessories I'm comfortable pushing the dress code limits with are shoes. In my opinion, the higher the heel, the better. For example, these heels are five inches, but really comfortable because of the platform. I wouldn't run any marathons or carry my child in them, but for the office, they work.

Although I like my heels to be sky-high, I also look for more conservative options that are comfortable. These red mary janes aren't really my style, but I decided to take a chance on them (thanks, Twitter feedback) and I think they're a win.

So, that's my week in clothing. It's not easy to dress in a way that makes me feel stylish within the confines of my corporate culture, but generally, I feel like my clothes show my personality. Happy shopping!
