Funnily enough I've just done a comparative review of a bunch of online MTM shirt makers -- including Proper Cloth -- and the shirt I got from them was that $85 white oxford. You can read the review here.
Good to see Proper Cloth on Styleforum. Some very good workmanship compared to other makers.
Many thanks for the great review! Don't forget you have a free alteration to dial in your fit even more. The first shirt looks great, but we're always happy to cut you a new one in an updated fit if there's something you think could be improved.
