You can wear anything you want to go out running. What matters is how comfortable you are in it. Back in the day whe I actually did outdoor exercise, the main thing for me was wearing something that I'd stay cool in. My kids go out walking/running for exercise some, and they usually just wear shorts and tshirts or sweats and tshirts. Sometimes they wear tank tops, and my son usually just wears shorts and tennis shoes, no shirt.
