How to Layer a T-Shirt for Autumn

Autumn outfits need to cope with changing temperatures: a cool start, a warmer indoor space and a different forecast by the afternoon. A T-shirt gives you a simple first layer that can stay in place while you add or remove the pieces above it.

The useful starting point is a comfortable tee, a middle layer with enough room and an outer layer suited to the weather. You do not need all three for every day; choose the combination for the conditions.

Get the base layer right

Check the fit before adding anything over it. Fabric that gathers under the arms or bunches around the waist will still be there once the shirt or knit goes on. A lightweight tee can sit neatly beneath other pieces, but comfort depends on the cut and the room available in each layer.

The current Core CV tees use 155gsm organic cotton. Choose your size from the product guide and check how it feels beneath the layers you already own.

1. A tee and an open overshirt

This is an easy combination for mild days. The open shirt adds shape and another texture while leaving the tee visible through the centre.

Try an Oat tee with an olive or dark navy overshirt and black trousers. The lighter base separates the layers visually. Alternatively, a black tee beneath a stone overshirt makes the outer piece more prominent.

Check the sleeve and shoulder room with both garments on. Button the overshirt briefly, even if you plan to wear it open, to see whether it pulls across the chest.

2. A tee beneath knitwear

A crew-neck knit gives the outfit a different surface and can work with denim or more tailored trousers. Decide whether you want the T-shirt neckline to show. A small visible edge can look deliberate; several collars competing around the neck may feel untidy.

A white tee creates a clear contrast beneath a dark knit. Navy or grey can make that contrast quieter. Check that the tee's sleeves sit smoothly and that its hem does not collect beneath the waistband of the knit.

If you prefer a visible T-shirt hem, choose a length difference that feels intentional when standing and sitting. There is no single correct amount; look at the complete silhouette.

3. A tee with a hoodie and jacket

For a more casual combination, add a hoodie and an outer jacket. Start with the thickest point: the hood and upper back. The jacket needs enough room there, as well as through the shoulders, to avoid restricting movement.

Keep the colours simple if the layers are substantial. A black tee, grey hoodie and dark jacket can work with blue denim. An Oat tee under navy creates a warmer contrast.

Choose the outer jacket for the forecast. A cotton tee and hoodie are not substitutes for a weather-appropriate outer layer when rain or cold is expected.

4. A tee beneath a blazer or structured jacket

For a cleaner casual look, pair a tee with a structured jacket and straight or tailored trousers. The neckline should sit comfortably beneath the lapels, and the body should not bunch when the jacket closes.

Dark navy, grey and black provide several easy combinations. A lighter tee brings more contrast around the face. Keep footwear consistent with the setting, and check the dress code if you are dressing for an event.

Keep the palette manageable

Start with two main colours and add a third only if it helps the outfit. Repeating a shade in your shoes, trousers or outer layer can connect the pieces. Using different textures within similar colours also gives depth without requiring more colours.

The aim is to make the layers work together when you wear all of them and when you remove one. Check the outfit with the outer piece off before leaving.

Move before you decide

• Raise your arms and reach forward.
• Sit down and check the fabric around the waist.
• Close the outer layer to assess the available room.
• Remove one layer and make sure the remaining outfit still feels comfortable.
