What does Superman wear ; under his costume (which is worn under ; a striped ;button-down shirt)? That's right -- he wears the ; Superman Black Men's V-Neck T-Shirt. Why? Because ;there are occasions when saving the Earth from sentient golden bullets from Dimension G actually finishes ;up before 10 PM, so there's time to shed the costume, reveal the V-neck, and join the still-forming Metropolis bar crawl. Made from 100% cotton, this Superman V-neck t-shirt for men features a bright, screen-printed, red and yellow Superman ;symbol. And yes, it's an optional costume change when the closest threat is an EDM festival and NOT Braniac.
