Mens plain white slim fit tshirts for teens

[londonevening]

My teen boys only want to wear plain white tshirts. I dont want to pay huge amount as they get trashed. Primark never have slim fit. Anywhere else do white cotton slim fit tshirts for under £10, ideally cheaper. Thank you

H&M

These, fruit of the loom are really good quality not to mention the low price

Thank you
I have tried H&M instore several times without success as always feel that should be an option. Do you know any specific products or is it online?
Are the fruits of the loom slim fit?
