To stop T-shirts shrinking, keep heat away from them: wash at 30°C or cooler on a gentle cycle, avoid high-heat tumble drying and reshape each tee while it is damp before drying it on a hanger or flat. Cotton tightens up when heat and agitation work on its fibres, and over-drying finishes the job. Control those three things and a good T-shirt will keep the fit you chose, which matters most when the tee is the base of a smart-casual outfit rather than something you sleep in.
Why T-shirts shrink
Cotton fibres are stretched and held under tension when yarn is spun and fabric is knitted. Heat, water and movement let those fibres relax back towards their natural, shorter state. The result is a tee that is shorter in the body, tighter across the chest or twisted at the side seams. Three factors do most of the damage:
- Hot water, which relaxes fibres quickly.
- Agitation, from a long or fast cycle, which tightens the knit.
- High-heat drying, which is usually where the biggest change happens.
Fibre content matters too. A 100% cotton tee tends to react more to heat than a blend with polyester or a little stretch, which holds its shape more steadily.
8 simple laundry rules
- Read the care label first. Our tees, including the Essential Cotton T-Shirt, are labelled machine wash at 30°C on a gentle cycle, do not bleach and tumble dry low. Treat that as the upper limit, not the target.
- Wash at 30°C or cooler. Everyday tees rarely need more. Use a hotter wash only for heavily soiled workwear, not your good T-shirts.
- Choose a gentle or short cycle. Less agitation means less tightening of the knit.
- Turn tees inside out. This protects the outer face and any print from rubbing.
- Do not overload the drum. Tightly packed loads twist and pull, which distorts side seams.
- Reshape while damp. Straight after the wash, give each tee a gentle tug lengthways and across the chest, and smooth the collar.
- Air-dry where you can. Hang tees on a wide hanger or lay them flat. If you use a dryer, choose the lowest heat and take them out while slightly damp.
- Keep them off radiators. Direct heat can shrink and stiffen cotton in one go.
How fabric weight and blend affect shrinkage
Fabric details on a product page tell you a lot about how a tee will behave. Here is how some pieces in our range compare, using their listed fabric data.
| Piece | Fabric | Weight | Care note |
|---|---|---|---|
| Essential Cotton T-Shirt | 100% cotton | 260 gsm | Cool wash, reshape damp |
| Heavyweight Drop-Shoulder T-Shirt | 100% cotton | 300 gsm | Cool wash, dry flat |
| Contrast-Collar Raglan Polo | 68.2% cotton, 25.5% polyester, 6.3% spandex | 220 gsm | Blend holds shape; still avoid high heat |
Heavier cotton tees feel more substantial and hang with more structure, which is why they suit smart-casual outfits under an open overshirt or jacket. They still respond to heat, so the same rules apply.
What to do if a tee has already shrunk
A little shrinkage can sometimes be eased out. Results are not guaranteed, but this gentle method is worth trying:
- Soak the tee for around 30 minutes in lukewarm water with a small amount of hair conditioner or a gentle fabric softener mixed in.
- Press out the water without wringing.
- Lay it on a towel and roll the towel up to absorb more moisture.
- Unroll, then gently stretch the tee lengthways and across the chest, a little at a time.
- Dry it flat, reshaping again halfway through.
This works best on modest shrinkage in cotton tees. A tee that has gone down a full size is usually better kept for the gym or lounging. If the collar has stretched rather than the body shrinking, our guide on how to fix a stretched collar covers that.
Buying a T-shirt that keeps its fit
Prevention starts at checkout. Check the fabric content and weight on the product page, look at the garment measurements rather than the size letter alone, and choose the fit you want to wear, not one you hope will shrink into place. A loose or drop-shoulder cut gives you a little more tolerance, while a fitted tee shows every centimetre of change. For a wider look at what to check, see signs of well-made clothes.
A quick weekly routine
Group tees by colour, turn them inside out, wash cool on a short cycle, reshape and hang. It takes a few extra minutes and keeps your best tees fitting the way they did on day one.
Frequently asked questions
Do all cotton T-shirts shrink?
Most cotton tees can shrink a little if exposed to high heat, especially in the dryer. Washing cool and air-drying keeps that change to a minimum.
Is it safe to tumble dry a T-shirt?
On a low setting it is usually fine if the label allows it, as ours do. Take the tee out while slightly damp and finish drying it on a hanger to protect the fit.
Should I size up to allow for shrinkage?
It is better to buy the fit you want and wash with care. Sizing up can leave a tee looking oversized in a way you did not intend, particularly across the shoulders.
