Seams
 

Study the Seams

Check where your shirt’s seams line up on your shoulders. If they trickle right below, then it’ll look like you aren’t big enough to fill out your shirt, says Brian Boye, Men’s Health’s executive fashion director.

But if the seams lie squarely on or just above your shoulders, they’ll look broader. “People will assume you’re so big that not even your shirt can contain you,” he says.
