Are there other girls who lounge around in a sports bra?

There's a girl I'm best friends with who has her own apartment and at the end of the day when she gets home from work she changes into a pair of girl gym shorts and a sports bra (sometimes she'll wear long pants with the sports bra). With warm weather coming back she lounges around, watches TV, reads, and sleeps in a sports bra. We talk all the time and I've been to her apartment before that's how I know this. Are there other girls who do this? Is she the only one?
