White vest
The secret weapon of boyfriend's arm is actually hidden in our daily clothes. White vest, seemingly simple, has a force to be reckoned with. It can not only show the broad shoulders and strong chest muscles of men, but also highlight the arms of boyfriends. In the gym, a white vest makes your biceps, triceps and shoulder lines unobstructed and becomes the focus of attention. More importantly, the white vest is simple but not simple, which allows you to easily show your fashion taste while exercising.
Therefore, if you want to have a boyfriend's arm, don't get a white vest and become the brightest light in the gym!
