I ordered 170mm and it is long. I'm 6ft 1" with a waist of about 35". 125mm would be too short, just an inch or less. It's okay, I'll cut something. The belt is slightly darker than in the photo. Not much but looks a lot better than the photo. The leather is thick and tough but of high quality and will soften/wipe off over time. I plan to use mink oil for softening and protection. The smell has a strong leather smell and I like it.
