Well I think you'll find that bald women are pretty rare outside the punk scene and a brief flirtation in the 70's (which gave us both Moondragon in comics and the Lt Iria character in the first Star Trek film). And it's undeniably an androgynous look.
But really, that was meant as just an offhand bit of snark, I didn't intend it to be taken so seriously or as the core of what I was trying to get at. And I'm more than happy to apologize to any whom I mistakenly offended.
However, I stand by my belief of the overall effect of the current costume as androgynous. It reminds me of the Robert Palmer girls in his "Simply Irresistible" video, or of 80s era Annie Lennox. And I just don't think that fits what Selina Kyle as Catwoman is all about.
For the record, I don't at all like how B:tAS gave us short-haired, skullcapped Selina. Her characterization was great, but those elements of her look sat wrong with me. And IMO if you're going to hide the hair, at least give her the tail and claws to emphasize the catlike profile as compensation.
On the other hand, you're right that a practical costume doesn't have to be androgynous or neutered. For a good example, look at the new sketches for the Batwoman costume. It's undeniably feminine, but it also is arguably quite a bit more practical than what Batman himself wears most of the time. It's proof in my mind that they didn't have to de-femme Selina, they just chose to. And I think it's a bad choice.
And it really does depend on the character. I love Rachel Summers, who's look has been quite butch for most of her career, especially under Claremont. And I loved the mohawk-and-leather era of Storm, more than any other incarnation. It -worked- for her. It wouldn't work for Selina.
Again, I'd have been fine with the look for Holly. She's a different character with her own style. Selina Kyle to me has certain attributes, strong among them the Femme Fatale elements that sometimes get ignored. Like now. And I miss them and want them back, that's all.
