100%. Don't see why not. Far too many hoodies as it is. Nothing wrong with dressing up for the job, and that goes for both genders. I used to wear a shirt and tie back in my customer support days, even if no one other than my colleagues saw it. The girl next to me always looked like she just stepped out of a fashion catalogue. If anything, I found it rather inspiring in a sea of unwashed faces, hoodies and ripped jeans.
