While I was shopping in a textile showroom here I found that different brands of the same size varies in their actual size. For example two branded shirts of 42 inch will be different in their actual size. I wonder how it happens as size should be the same anywhere in the world as it is a universal parameter. So I always use their trial room before finally buying clothes. I also avoid online purchase because of this fear. There is no consistency in sizing among different brands . Have you ever experienced this when you buy clothes online / offline?
