I've heard that from friends. She said international marriage with caucasian getting popular recently and some old men watching some women in train like that.
Think positively, why they watch you is just you got attention from others.
I guess you look outstanding as good meaning. Some of my western friends said if you were watched by others it means you look good or you have something special others never had.
Even though this case was Japanese old men, I guess that proves you are being watched and interested by some young nice Japanese men in train by your powerful attention fashion or makeup as well.
I know old men scary but if you wish to get to know many young nice male friends or partner, I think that fashion is not always bad.👍
BTW the story was heard by a female friend who used to be modeling in Tokyo from States.After that she married a nice Japanese stranger talking to her in public.
It's an example but you know old men are not always bad.😄Here are many nice old men👍
