Need a recommendation for good quality kids t shirts

[gigantosaurusisreallyenormous]

My daughter is 6- and everywhere I guy her t shirts when they wash they change shape or size etc. I just want some really good quality t shirts that will keep their shape and not break the bank.
Recommendations please

I have always found that ones from Primark, Asda, Pep and Co and Sainsbury's perfectly fine. Never had an issue with them. Always in good condition to pass on when outgrown.
