Shirts measured two inches bigger than the size guide but after sending them back Workwearexpress just returned them to me saying the supplier says they fall within their tolerance. Also Workwearexpress list two sizes, which is unusual and you don't spot or expect this. They list the garment size (say Large = to fit 42/44" yet they also, two lines down, state the garment size of 46" (mine actually measured 48" so massive on a 42" chest). So, for a 42" chest I should have ordered a Medium at 40"! I have wasted £124 buying shirts that are way too big and that are bigger than the size guide; so my problem!
