How to Wear a Check Blazer: Glen Plaid, Windowpane, Tartan and More

The short answer: a check blazer is a jacket woven with crossing stripes that form squares. Wear it with plain pieces in one colour pulled from the check, such as a camel knit under a brown check, a navy trouser under a blue one, and let the jacket do the work. Small, tonal checks like glen plaid are the most versatile; bold windowpane and tartan make more of a statement.

Checked tailoring is having its biggest moment in years, helped by the Princess of Wales, whose check coats and blazers from Blazé Milano send searches up every time she wears them. This guide explains the main checks, how to wear each one and where to find the best.

How to wear a check blazer

Pick one colour from the check

Look at the check, find its quietest colour and wear that underneath: a camel knit with a beige and brown check, a navy roll neck with a blue one, a cream shirt with a grey check. The outfit looks considered.

Match it, for a suit

A check blazer with its matching trousers is the most striking way to wear it. Blazé Milano cuts many of its checks as full sets, from Corinthian Grey to Moat and Langley; see every set in Blazé Milano suits.

Make it casual with denim

A brown check blazer, a white T-shirt and straight blue jeans is the easiest weekend look there is. More in how to wear a blazer with jeans.

Go tonal for evening

A grey check blazer with grey trousers and a silk camisole is glamorous without shouting.

Brown check, grey check, tartan: which to choose

Brown check is warm and easy, best with camel, cream, denim and burgundy, and the colour of the season. Grey check is the most versatile, as easy with black as with navy. Tartan is festive and heritage, at its best from late autumn through the holidays, and with plain black and deep red. Blue check is fresh and suits navy and white.

Check blazers by occasion

Why check tailoring is everywhere

Checks carry the codes of English country dressing, the shooting jacket, the estate tweed, the Prince of Wales suit, and in women’s tailoring they read as quietly confident rather than corporate. They also solve the problem of the plain suit: a check jacket looks finished on its own with jeans, while a plain one often looks like half a suit. And the Princess of Wales has made the check coat and blazer her own, which has turned a heritage pattern into one of the most searched looks of the year.

Check size and your frame

Scale matters. Small, tonal checks suit every frame and are the safest first buy. Large windowpanes and bold tartans add visual width, so petite women should wear them in a cropped jacket, and choose a plain trouser to keep the line long. Tall women can carry large checks head to toe as a suit. If you love a bold check but feel overwhelmed by it, choose it in an oversized blazer worn open: the open front breaks the pattern into two narrow panels.

Caring for a check blazer

Check tailoring is usually wool, so brush it after wearing, rest it between wears and steam rather than press. Have it professionally cleaned when needed, and always follow the care label. Store it on a broad hanger so the pattern hangs straight at the shoulder.

Pattern mixing

A check blazer can be mixed with a fine stripe shirt when the scales are very different. Avoid two checks of a similar size. When in doubt, plain underneath.
