Well, I don't know what your field is and if you're in something like finance, then there probably are people with very rigid attitudes in positions of power. In my field, though, and others, it's people destined NOT to be in leadership who conform.
In my field, where there are few women, it used to be that we couldn't go near anything feminine. These days, I have realized that I can demonstrate power and/or just do what I want with a couple of items as long as I do also wear items that a TV lawyer would wear.
I'm looking for a bag to take to a conference, as I usually don't need one with handles to get my laptop to my office, and I'd be fine with the OP's choice since the rest of my outfit is sophisticated. If I looked completely boring, people would (and I'm not being paranoid; there's a lot of judgment towards women) interpret that as a sign of weakness and stuck-in-the-lower-ranks-and-trying-to-impress,.
