Older boys red tartan (plaid/check) trousers quest

[Serenitesanta]

Can anyone please help me find a pair of dressy but not too formal red/blue tartan trousers for a boy aged 13yrs.
They must be traditional red tartan but not a particular tartan and I don’t want to spend over £25, preferably Vinted if possible!
All I can find are loungewear or green/beige ones
I thought I’d have loads of choice but 🤷‍♀️

@Serenitesantasorry…forgot to tag you.

@BamberGirl thank you so much, I might take a chance on those M&S ones and like the mustard ones. Definitely more comes up on search for check trousers

@Serenitesanta No problem, hope they work!

You could look at women or girl trousers. There’s some skinny jeans style hey might work? Could be a waist issue if cut for women’s hips though.
