I feel men feel easily repelled from me without even talking? What could be the reasons?

Is it my appearance or vibes I give off causing this? I am a 22 year old girl from India. I have experienced this a lot of time. Guys, even shopkeepers would be rude to me. I have my COVID mask on all the time so it's not like they can see my face completely and decide whether I am attractive or not and behave accordingly. I dont understand what strange thing do they pick up about me in one or two interactions that they decide to be rude to me. And it has happened a lot of of times now with many different men. Please tell, this has been getting me stressed out so much. Seriously, what is that one category of girls you would hate by just seeing her.
