I've met a few female-presenting people who can, and you share certain traits with both of the ones who come to mind. One, I would describe as "otherwise young-looking, dark-haired, with force of personality". She had long hair, and was a student with me in one of the math classes I took, and her silver streaks kept catching my eye - they were the kind you'd find on a suspiciously Mary Sueish character description on a MUSH, back in the day, and it's hard to describe it in any way but that - the bright silver against the dark hair just spoke of hidden awesome.
Another would be my general chemistry prof, who... the minute I walked into her class I looked up at her and thought, I want to look like that when I grow up. She's... late-middle-age-something? -- has one of those youthful faces, has grey hair and wears it short, but not the way that many older women do: she has the same haircut that I got them to give me once when I walked into a barbershop with a picture of Humphrey Bogart (which is not to say the same haircut as Humphrey Bogart, but the kind that frames faces like hers and mine similarly.) She manages "grown-up tomboy" in a hardcore, serious scientist way. It's kind of hard to describe. (Here's a picture of her, though it doesn't convey the full awesome of her presence.)
