T-Shirt Size Chart: Find Your Perfect Fit in Ireland

When you buy a T-shirt size chart, a standardized guide that matches body measurements to garment sizes. Also known as clothing sizing guide, it’s the only thing standing between you and a shirt that fits—or one that looks like it was bought for someone else. In Ireland, where body types vary and brands like Bench, Zara, and local makers use different cuts, a size chart isn’t just helpful—it’s essential.

Most people assume a medium is a medium, but that’s where things go wrong. A size M from Bench might fit like a large from H&M, and a small from an Irish brand could be tighter than expected. Why? Because Irish retailers design for our build—often broader shoulders, shorter torsos, or fuller hips compared to US or Asian standards. A men’s T-shirt fit, how a shirt sits across the chest, shoulders, and sleeves needs to allow room for layering under jackets in winter, while a women’s T-shirt sizing, how a top drapes over the bust, waist, and hips should avoid pulling at the seams when reaching for the kettle or carrying groceries. And don’t forget sleeve length—too short, and you’re stuck with armpit exposure; too long, and you look like you borrowed it from your brother.

What you wear under your coat matters. If you’re layering a thermal or hoodie underneath, you’ll need extra room. If you’re going for a slim look in summer, go true to size or even size down. But if you’re shopping online and can’t try it on, always check the actual measurements—not just the label. A size L might say 44 inches across the chest, but if your chest is 42, that’s still roomy. And if you’re between sizes? Go for the larger one. Irish weather doesn’t care if your shirt is snug—it cares if you’re comfortable. You’ll find that in our collection below: real reviews, real measurements, and real advice from people who’ve worn the same shirt through rain, pubs, and weekend walks. No fluff. Just what fits, what doesn’t, and why.
