Which color? In the black, I'd say yes. The pink is more of a stretch depending on how conservative your coworkers are.
Yep! The black one. Generally, I'm not a big fan of pink on me.
One other question. I'm just not sure what type of top would be appropriate with it and keep it business casual. Maybe a button down shirt with a cardigan? I'm not very creative with my fashion, but am really trying to be a little less blah with clothes.
