Bridgit Mendler wore a Black New York City Muscle Tee in her Music Video for the Song "Hurricane -Bridgit Mendler"
Unfortunately I couldn’t find the exact shirt buy a found a couple which were similar. This one shown is Nasty Gal New York City Muscle Tee which is sold out in black. Which looks like THIS
in black. And the Forever21 which has the same print just has a colorblock section.
