Any suggestions where to look for men's casual shirts please?

Hi, I'd like to buy DH a smart casual shirt for Christmas but not sure what are considered decent brands today...any ideas? Looking to spend up to £50.

My dp swears by muji shirts. May not be what you're after, but worth a look.

Charles Tyrwhitt, always promotions online. I got a really nice casual button down shirt for £30,was £70. Quality is good and the fit is generous {they also do slim & super slim fits}.
