Designer clothes are kind of a last bastion of shitlordiness.  They refuse to dilute their brand by making clothes any fatty can wear, then fats complain they can't find anything (though if they go where they're supposed to [i.e. Walmart] they could).  I'm honestly surprised the FA twats haven't petitioned for some sort of legislation that requires garment manufacturers to offer clothing for all sizes.  It would totally fit their narrative.
