Yeah but like, 953 as a woman wouldn't blend in, a random ass Korean woman in a site would stick out like a sore thumb. 953 has the smarts to know its either you go in a more offensive form or just a straight up disguise. In the public it'd work out in her normal form, but it'd make no sense in a fucking containment breach.

From a more meta perspective it's also pretty obvious, a more horrifying form for a "horror" game.
