A mum has revealed an amazing feature on M & S school trousers for when kids grow too tall.
The woman took to Facebook to reveal that the trousers have a secret hem.
This handy feature means that the trousers can be extended by 3cm – so you can get more bang for your buck, writes the Mirror.
According to the M&S website, grow-proof hems add an extra 3cm onto the length of the trousers to help them “last all year”.
Stunned by the secret feature she took to the Family Lockdown Tips Ideas group on Facebook writing: “I was today years old when I found this out about M&S school trousers!
“How did I not know this? There is actually a proper double hem!!”
It says: “Just unpick and press for an extra 3cm. Added stretch and an adjustable waist for a perfect fit.”
All you have to do is cut along the blind stitching, remove the thread, let down the additional material and press.
The ‘Skinny Leg Ultimate trousers’ are stain and waterproof as well as crease resistant.
Unsurprisingly the post received a lot of attention from fellow parents with over 5,000 likes and tonnes of comments.
One person admitted: “I’ve always bought M&S trousers, how did i not know.”
Another added: “I have never seen this thank you.”
And others praised the savvy woman for sharing.
