This belt fits through most belt loops and stays in place. It is thin and does not show under shirts. I also use it on pants without belt loops. Some of my pants move when I get up and down (chasing toddlers) the belt then moves too. I have fixed this with safety pins that I weave the belt through. This is a great form fitting belt. Ive bought 2 others and given them to my sons to tie my grandsons into high chairs. So many restaurants have broken straps. It works great for that purpose too.
