Quick answer: A well-fitting shirt lets you slip one finger inside the buttoned collar, has shoulder seams at the edge of your shoulders, sleeves that end at the wrist bone and enough length to stay tucked when you raise your arms.
Why fit matters more than price
A modest shirt that fits well looks better than an expensive one that does not. Fit is what makes a man look put together: a collar that sits cleanly, shoulders that line up, sleeves that end in the right place. The good news is that shirt fit follows a few simple rules. Once you know them, you can check any shirt in a minute in front of a mirror.
The collar
Button the top button. You should be able to slide one finger, maybe two, between the collar and your neck. Any tighter and it pinches; any looser and the collar collapses under a tie. If you rarely button the top, the collar still matters, because a well-sized collar stands up neatly and frames the face. Our size guide lists neck measurements for every size.
Shoulders and chest
The shoulder seam should sit right at the edge of your shoulder bone, not halfway down your arm and not up on your neck. Across the chest the fabric should lie flat with no pulling at the buttons and no big folds of extra fabric. A classic oxford shirt is usually cut a little roomier through the chest, which makes it comfortable for all-day wear.
Sleeve length
With your arms at your sides, the cuff should end at the wrist bone or just past it, so a little cuff shows beyond a jacket sleeve. Raise your arms: if the cuffs ride far up your forearm, the sleeves are too short. Sleeves should be slim enough not to billow but loose enough to roll comfortably when you want a casual look.
Shirt length
A shirt meant to be tucked should be long enough to stay in when you reach up or sit down, roughly covering your seat. A shirt meant to be worn untucked, like many linen and casual shirts, should end around the middle of your fly. Too long untucked looks sloppy; too short tucked keeps escaping. Check the style before you choose.
Linen for warm days
Linen is the most comfortable shirt fabric for heat and humidity. It breathes, dries fast and gets softer with every wash. A men's linen shirt works tucked into trousers for a summer office or untucked over shorts at a cookout. Embrace the natural creases, or steam it before you leave the house for a smoother look.
Oxford cloth for every day
Oxford cloth is a sturdy basket-weave cotton that feels soft and looks smart. The button-down collar keeps the points in place with or without a tie. An oxford is the single most versatile shirt a man can own: with a tie and blazer for work, open-collared with chinos on Friday, and untucked with jeans on the weekend.
When to choose an overshirt
An overshirt is heavier and cut roomier so it can be worn as a light jacket over a tee or a thin knit. It is perfect for cool fall days when a coat is too much. Wear it open with jeans and boots, or buttoned with chinos. Choose your usual size if you will wear it over a tee, and one size up if you want room for a sweater.
Care and storage
Wash shirts cold on a gentle cycle and hang them to dry on a hanger, buttoned at the top, to keep their shape. Iron oxford shirts while slightly damp for the crispest finish, and steam linen. Store shirts on wide hangers with space between them. Browse our shirts in sizes S to XXL, each with a full size guide and free U.S. shipping.
