Girls, Why she randomly walk up to be and compliment my clothing?

Saw a girl in the gym that Ibhd never seen before. I was busy kinda working out, and so was she. She caught my eye a little but and I stole a few glances. She looked kinda cute.

Then a while after before she left, I was minding my own business. She walked right up to me in gym and told me she liked my jacket. I said thanks , then she just left?

Why did she randomly walk right up to me and compliment my clothing? We don't know each other
