Show me a smaller pair of trousers , sir . I am not that fat , you see .   You've come to the right place . We've got various styles and sizes recently . How much do you measure around your waist ?   I have no idea . Measure me , please .   OK ! 2 Chi round . Try this one . Maybe it's of your size .   ( After trying ) I'm afraid it's still too fight around the stomach .   Let me check the stock . How about this one ?   ( After trying ) Mm , a perfect fit . How much ?
