FAQ

Q: Why does the design look bigger on a 3XL than on a Small?

A: Our prints scale with your shirt size so it always looks balanced—smaller tees get a cozy 10–12″ print, while larger sizes get a slightly bigger version to fill the chest area just right.

Q: Are these shirts unisex? Why are some models women?

A: Yep—every tee is unisex and designed to look good on all body types. We mostly speak fluent dude here (gamers, jokesters, traders—you know the crew), but these shirts are for anyone who loves a good laugh, deep lore, or a perfectly timed meme. You’ll see both men and women in our mockups to help show the fit. Whether you’re built like a tank or a stealth rogue, we got you.

Q: I see female models styling this tee—do you offer women’s cuts?

A: These are unisex crew-neck tees designed to look great on every body. We model on different frames so you can preview how it drapes. If you want a snug fit, size down; for a relaxed look, size up.

Q: How do I know what size to choose?

A: Refer to our size chart for exact measurements. If you’re between sizes, go up for a looser fit or down for a closer fit—whatever feels most “you.”
