Yep. I know that other people react differently, but when I was a physics student, being aware that I was gender integration on two feet made "femininity" whatever I said it was. There's nothing more feminine than my own self in a pair of hiking boots, jeans, a flannel shirt, and an Einstein T-shirt, attaching modules into a NIM bin. I've worn gold sparkly pumps and a cleavagey red evening dress, and it had absolutely nothing on the boots etc. for femininity.
