Overwashing your clothes could be ruining them faster than you think.
Most of us automatically throw clothes into the laundry basket after a single wear. But in reality, many garments can be worn multiple times before they need washing - helping your clothes last longer while reducing water, energy use and microfibre pollution.
The fashion industry already has a significant environmental footprint, but what happens after we buy our clothes matters too. In fact, research from Plymouth University found that washing a single 6kg load of clothing can release hundreds of thousands of microfibres into waterways - particularly from synthetic fabrics like polyester and acrylic.
The good news?
A few simple changes to your laundry routine can:
- Extend the life of your clothes
- Reduce fading, shrinking and fabric damage
- Lower your environmental impact
- Save water and energy
So, how often should you really wash your clothes?
Here’s your complete guide.
How Often Should You Wash Clothes?
How Often Should You Wash Jeans?
Denim is one of the most durable fabrics in your wardrobe - but it’s also one of the most overwashed.
Frequent washing can:
- Fade colour
- Break down fibres
- Cause jeans to lose their shape faster
In many cases, jeans don’t need washing after every wear unless they’re visibly dirty or stretched out.
Recommended:
Wash jeans every 10-15 wears
Between washes:
- Air them out overnight
- Spot clean marks
- Steam to freshen and remove odours
Steaming is especially useful because it refreshes denim without causing unnecessary wear.
Top Tip
When washing denim:
- Turn jeans inside out
- Wash cold at 30°C or below
- Avoid overloading the machine
A gentle fabric conditioner can also help prevent stiffness without damaging fibres.
How Often Should You Wash Cotton T-Shirts?
T-shirts sit directly against your skin, so they naturally absorb sweat, oils and deodorant more quickly than outer layers.
Recommended:
Wash after 2-4 wears
However, this depends on:
- Weather
- Activity level
- Fabric type
A loose cotton T-shirt worn for a few hours may not need immediate washing, while fitted synthetic tops usually need more regular cleaning.
Top Tip
Wash T-shirts inside out to:
- Protect colour
- Preserve printed graphics
- Reduce fading
Lower temperature washes are also much gentler on fabric and use significantly less energy.
How Often Should You Wash Bras?
Bras are one of the most commonly overwashed items in the wardrobe.
Frequent washing weakens elastic fibres and shortens their lifespan dramatically.
Recommended:
Wash bras every 3-4 wears
Sports bras are different and should be washed after every workout.
Top Tip
Hand washing is always best for bras, but if machine washing:
- Use a mesh laundry bag
- Choose a delicate cycle
- Avoid tumble drying
Heat is one of the quickest ways to damage elastic.
How Often Should You Wash
Sweatshirts & Hoodies?
Hoodies, sweatshirts and jumpers are outer layers, meaning they typically stay cleaner for longer than items worn directly against the skin.
Recommended:
Wash every 5-6 wears
Unless:
- You’ve been exercising in them
- They’ve absorbed strong odours
- They’re visibly stained
Top Tip
Overwashing fleece and synthetic hoodies releases microplastics into waterways. Washing less frequently and air drying wherever possible can help reduce environmental impact.
How Often Should You Wash Gym Clothes?
Unfortunately, activewear is one item that really does need regular washing.
Sweat, bacteria and body oils build up quickly in performance fabrics.
Recommended:
Wash after every wear
But there’s a smarter way to do it.
Top Tip
Use cooler wash temperatures and avoid fabric softener on sportswear, as it can reduce moisture-wicking performance.
Air drying is also better for elasticity and helps activewear last longer.
How Often Should You Wash Pyjamas?
Pyjamas absorb sweat and skin cells while you sleep, but they don’t usually need daily washing.
Recommended:
Wash every 3-4 wears
If you shower before bed, you may be able to wear them longer.
Top Tip
Natural fabrics like cotton and bamboo tend to stay fresher for longer because they’re more breathable than synthetic sleepwear.
How Often Should You Wash Shirts & Blouses?
Work shirts and blouses usually sit close to the skin and often pick up deodorant, oils and perspiration around collars and cuffs.
Recommended:
Wash after 3-4 wears
Top Tip
Instead of overwashing delicate shirts, try steaming or spraying between wears to refresh fabric and remove creases.
Steaming can kill bacteria while being much gentler on fibres than repeated washing.
How Often Should You Wash Wool Sweaters & Cashmere Sweaters?
Wool and cashmere are naturally antibacterial, breathable and odour-resistant - meaning they need far less washing than most people think.
Recommended:
Wash every 10-15 wears
In many cases, simply airing garments out is enough.
Top Tip
Always:
- Wash cool
- Use a gentle detergent
- Dry flat
Never wring wool or cashmere, as this can distort the fibres and cause stretching.
Using a specialist detergent designed for delicate natural fibres can also help preserve softness and shape.

How Often Should You Wash Jackets & Coats?
Outerwear usually only needs occasional cleaning unless exposed to heavy dirt, smoke or rain.
Recommended:
Clean once or twice per season
Top Tip
Spot cleaning and steaming can dramatically reduce the need for full washing or dry cleaning.
Leather and suede jackets should be conditioned rather than washed to prevent cracking and dehydration.
How Often Should You Wash Towels?
Towels trap moisture, making them a breeding ground for bacteria if left too long between washes.
Recommended:
Wash every 3-4 uses
Top Tip
Allow towels to dry fully between uses to prevent musty smells and mildew buildup.
Avoid using too much detergent or softener, as this can reduce absorbency over time.
How Often Should You Wash Bedding?
Bedsheets collect sweat, oils, skin cells and dust mites surprisingly quickly.
Recommended:
Wash bedding every 1-2 weeks
Pillowcases may need more frequent washing, especially for sensitive skin.
Top Tip
Washing bedding at lower temperatures with a quality detergent is often enough for regular maintenance while reducing energy use.
Is Washing Clothes Too Often Bad?
Yes - overwashing is one of the biggest causes of clothing damage.
Frequent washing can:
- Fade colours
- Weaken fibres
- Cause shrinking
- Reduce elasticity
- Shorten garment lifespan
It also increases:
- Water usage
- Energy consumption
- Microplastic pollution
Learning when clothes actually need washing is one of the easiest ways to make your wardrobe more sustainable.
