I wear 36 trousers, jeans etc. I ALWAYS buy XL belts. This XL belt is VERY BIG. Adjusting (through the holes in the belt) I can slide the belt from my waist down through my hips to the floor. IT'S GIANT for size XL. The seller/manufacturer isn't very helpful on this site in terms of sizing, but I figured since I have tons of XL belts, a size XL would be ok. TOO LARGE. THIS IS HUGE. I see another reviewer who stated that it's too small for an XL belt. I wonder if they mislabel them? Finally, the belt says it's REAL LEATHER, but it's not. It's faux leather as advertised, but the belt itself says GENUINE LEATHER. I think they are stamping the wrong size on these straps as well as the material they are made of. The price is cheap so I just ordered a LARGE to replace this EXTRA LARGE. I will report how this size relates to this very large version.
