I love charity shops.
Definitely notice that a size 12 today is a size 6 from 20 yrs ago.
That older clothes are cut better and better quality overall.
I can buy two Monsoon outfits for DTwins for £1.50 (children's clothes are all 50p each or 3 for £1!!!) Or go to Monsoon and pay £80-100 for the same.
Despite being able to afford it, I will not buy any new clothes for DC except on rare occasions. They stain them, put holes in the knees, outgrow them at an astonishing rate. With charity shops, FB marketplace and the like, I don't care if things get trashed on the first wear. I was cross when boy twin wore his £50 trousers for the first time at a wedding and grass stained them the moment we left the church.
It makes me realise that the £40 I save on each pair of M&S autograph trousers for DH (on his third pair from a charity shop now) is £40 for fillet steak for tea, or a birthday present for Nan, or diesel in the car. It's a no brainer.
Less landfill. Donating to charity. Saving thousands a year. The satisfying feeling of a great bargain. Certainly for clothing, and glassware too, it's made me feel the high street is falling fast behind.
