The basics
What to know about classic fit
Classic fit, often labeled regular, is the cut a maker drafts its size chart around. It usually carries 4 to 6 inches of ease at the chest with a straight, unsuppressed waist. Every other fit in the range is graded outward or inward from this base pattern. So classic is where a brand's sizing is most accurate. Sleeve and leg widths follow the same logic, cut wide enough that the crease falls straight without clinging.
Worn, the cut allows a full forward reach without the back pulling, and a thin knit layers underneath without strain. Tucked shirts blouse a little at the waist, about a finger's width of fold, which is the traditional look in conservative offices. Because nothing grips, classic hides lunch, travel and the 5 pounds that come and go through a year.
What you give up is definition. On a slim build the straight waist can read boxy, since 6 inches of ease has nowhere to sit. A quick test: pinch the shirt at your waist side seam, and if you gather more than 3 inches of cloth the cut is wearing you. Brand drift is the other thing to watch, since one maker's classic is another maker's relaxed. Classic dates a wardrobe least, so it suits garments you intend to keep 5 years or more.
