So what actually works for daily wear? Start with your routine. If you're on your feet, moving, or layering, regular fit wins. It's easier to tuck into jeans, wear under a hoodie, or keep out of the way. If you're mostly seated, lounging, or want a statement piece, oversized fits that energy.

A good default: choose regular fit for any tee that's part of a uniform—like a black or white basic. Save oversized for graphic tees or weekend pieces. This gives you maximum versatility without overthinking.

Fabric matters more than fit. A medium-weight cotton (around 6 oz) holds shape in both fits. Too light and it wrinkles; too heavy and it feels stiff. Look for a soft, breathable fabric like combed cotton or a cotton-poly blend for everyday comfort.
