A short, practical selection rather than an exhaustive one. The useful question with a shirt is what you intend to wear it with, because that decides the cut more than the colour does.

Standard shirts are cut to tuck in and to sit under a jumper or blazer without bunching at the waist. If you mostly wear a shirt to an office, this is the shape you want, and a neater fit will layer better than a relaxed one. Overshirts are the opposite idea: cut longer and looser, meant to be worn open over a T-shirt as a light layer rather than tucked in. They are effectively a jacket that packs like a shirt.

Polo shirts sit between the two. Collared enough to pass as smart-casual, comfortable enough for a warm day, and the easiest thing here to wear without ironing.

Sizing. Fit is stated on each product page where the supplier specified it. If you are between sizes and plan to wear a jumper over the top, take the larger — a shirt that pulls across the back is the first thing to become uncomfortable.

Care. Follow the label; cotton-rich shirts hold their shape better hung than folded.
