Find the Perfect Fit
 

A well-fitting shirt will accentuate your biceps and chest, but there’s a big difference between snug and skin-tight, says Boye. “Choose the size that hugs your arms and shoulders, but not your mid section.”

Go with a cotton T-shirt with a 1- to 5-percent stretch. Shirts in this range don’t wrinkle as much, and cling to your frame more than all-cotton tees, Boye says. He recommends the Stretch T-shirt from H&M.
