Zero Crunches, All Flex
Who has time for meal prepping, deadlifts, and whatever burpees are? Skip the gym and go straight to the gains with this Plus Size Muscle Shirt. It’s the ultimate shortcut to looking jacked without ever lifting anything heavier than a remote control. Perfect for costume parties, superhero transformations, or casually intimidating your cousin at Thanksgiving.
One shirt. Two sleeves. Infinite delusions of grandeur.
Design & Details
This pullover shirt is made of soft, stretchy jersey knit fabric that’s comfy enough for a whole evening of fake flexing. The chest and arms are stuffed with fiber-fill to give you that bold, bulging, “I definitely curl trucks for fun” silhouette. It's lightweight, breathable, and gloriously extra.
Printed shading adds that realistic muscle definition—pecs, biceps, abs, and everything in between—without a single gym membership required. Just pull it on, pair it with literally any pants, and boom: instant hunk status.
Flexin’ Without the Effort
Forget protein shakes. This shirt is all the bulk, none of the sweat. Whether you're playing the hero, the heartthrob, or the guy who “totally used to bench 300,” this top’s got your back—and your biceps, and your pecs. Now go forth and shirt the system.

We believe that costumes have the power to create some of life's best moments. That's why we started Made by Us. This diverse selection of costumes and accessories are all artfully designed and expertly crafted by our talented team of artists, designers, and developers.

Each project begins with a passion for true quality–embroidered patches, faux fur cut with care, and hand-selected fabrics that are as durable as they are comfortable. Those are just a few examples of how much craft and creativity we put into each and every product. Just for you.

No matter how much time it takes, our goal has always remained the same–to create products that inspire your life's best moments–the big, the small, the funny, the spooky, and the sweet. The moments we all cherish. That's Made by Us.
