The top has grown longer than when you bought it
Sep 20, 2026
Short answer: A sweater gets longer because the weight of the fabric pulls it downward, mostly when it hangs wet. Drying it flat brings it back to its original length, so there is no need to buy a new one.
The weight does the work
Wet knit weighs three times as much as dry knit, and when it hangs freely, its own weight stretches the stitches downward. It happens slowly, so you rarely notice it from one day to the next. Long styles such as women's bamboo tops are affected most. Read on to see how you get the length back.
It is not a flaw in the fabric
Knit is elastic and gives way to a pull, which is also why it can be pulled back again. This is a normal trait of knitted materials, not a sign of poor quality. It applies to sweaters and to bamboo underwear for women alike. As long as the stitches are intact, the shape can be restored.
How to get the length back
Wash the sweater as usual, lay it flat on a towel, and gently push it together lengthwise until it reaches its original measurement. Smooth the sleeves and hem so it lies evenly. Then leave it to dry undisturbed. The method works on every knitted layer, including a bamboo hoodie for women.
Let it dry undisturbed
When the sweater lies flat, nothing pulls on the stitches while they dry. Leave it alone until it is fully dry, because it keeps the shape of its last drying. Choose a spot with good airflow but no direct sun or heat, so the fabric can settle at the right length.
Skip the hanger for wet knit
A wet sweater on a hanger is the fastest route to a longer sweater. The weight gathers at the shoulders and pulls all the fabric downward while it dries. Use a drying rack where the sweater rests over several bars, or lay it fully flat. That spreads the weight, and the length stays the same.
Do not wring out the water
Wringing a wet sweater stretches the stitches even further, and the damage only shows afterwards. Instead, press the water out by pressing the sweater lightly against a dry towel and rolling both together. It dries faster that way, and the fabric is not pulled out of shape. This suits long and short styles alike.
Measure before and after
If you have a sweater you love, measure the length from shoulder to hem the first time you wear it. Write it down or remember it. After a wash you can see whether the sweater lies as it should and push it to the right measurement while it dries. A tape measure is all you need.
Repeat it with every wash
Flat drying does not work once and for all. If the sweater hangs wet again, it is stretched again, so the method belongs to every wash. Make it a fixed habit, and laying the sweater in place takes a moment. Over time it becomes as natural as sorting the laundry, and the shape stays good.
Frequently asked questions
Will it grow longer again
Yes, it stretches again if it hangs wet. Flat drying has to be repeated every time, and then the sweater keeps its length without any extra effort from you.
How much length can you win back
Typically two to four centimetres. A bigger difference means the sweater has been stretched over several months, and it may take several rounds of flat drying to recover it.
Is it better to buy a shorter style
No. Length is rarely the problem, the drying method is. A shorter style stretches too if it hangs wet, so flat drying is the better fix.
