This year I went for the mischievous cat look. I pulled this off last minute because I was struggling to find something that is "work appropriate" to wear. And then I put this together.

I wore a white dress buttoned shirt with a red bow, layered underneath a black round crew neck top.
I was so glad that I found this Dr. Seuss Hat from working part-time at Burger King centuries ago. What a last minute win!
