I just got a tape and started some measuring to work out where I went wrong .
I cannot find my mm measure , and don’t have a 32mm belt to hand but looked at a canvas work belt ...
I think my confusion might be caused by trousers rather than belt sizes
I have a few pairs of Armani jeans , all will take a big belt easily and some will take my work belt through the leather badge thing that’s on the back between the belt loops .
But some pairs will not . The leather thing is too narrow for the belt to go through .
Not a big problem , as I never put my belt through that thing anyway as it’s normally covered by an un-tucked shirt AND it’s too fiddly and takes too long ...
I pride myself on being able to get showered , dressed , and ready to go within 10 minutes .


However , the pairs that it will not fit through are the pairs that have silly metal bits on the leather ....
If you have any jeans with metal bits on that leather thing I advise you to measure first BEFORE you buy a reversible belt , as they will no doubt mark the “inside” leather making it kinda irreversible .
