Frequently asked questions

Can you wear a t-shirt under a suit or blazer?

Yes. A plain crew-neck tee in a neutral colour — black, white, grey or navy — works well under an unstructured blazer or a relaxed suit for a modern, tie-free smart-casual look. Keep the fit close so it sits cleanly under the jacket.

Which t-shirt weave looks dressiest?

Ribbed and knitted styles read more elevated than basic cotton. The knit texture gives a tailored, considered finish that pairs naturally with blazers and trousers, while classic cotton is best for everyday wear.

What should I wear with a plain crew-neck t-shirt?

Pair it with casual trousers or chinos and loafers for a polished off-duty outfit, or layer it under a blazer or overshirt for smart-casual occasions. See the full smart-casual range for matching pieces.

How should the t-shirt fit for layering?

Choose a regular fit if you'll wear it under a jacket — it sits flat without bunching. Relaxed and raw-edge styles work better worn on their own for a looser, modern shape.

Which colours are the most versatile?

White, black, grey and navy go with almost anything and layer easily under tailoring. Olive, khaki and beige add an earthy option for casual outfits.
