Thats not a tomboy. The butch lesbians are actually tomboys since they dress like Cis heterosexual men.
That looks like a girl dressed like a gay boy who dresses effeminately.
A Cis heterosexual straight man wouldn't be caught dead with that haircut in those clothes.

they're generally not straight, but they can be bi.

What kind of question is this?
That's like asking if all lesbians wear flannel, or if all gay men are flamboyant.
No, of course not.
