Since boyhood I have threaded my belts, from a bird's eye view, clockwise around my waist, that is to say, ending with the buckle pointing to my left & the tail end of the belt to the right. A few years ago I bought a belt with a logo on it which was upside down when it was tied.
I started looking around & realised I was in a tiny minority who do so, one is Michael Portillo another is Prince Harry & to my horror I noticed, watching a documentary on TV the other night, so did Adolf Hitler !!!
I hope there are no lessons to be learned from this. :0)
