Lol this is highly dependent on who you talk to. When I worked during college, my 18-23 year old female coworkers didn’t refer to themselves or each other as a “woman” but rather “girls.” In fact they scoffed at our manager because she criticized them for tardiness, saying it was “unprofessional for young women”, which they later confided to me to “no shit we’re not fucking old!”

But I’ve also met female students who are laser focused on education or corporate ladder climbing who refer to other people our age as “women”
