Haven't worn it but a couple hours so far, hoping it doesn't come undone as some ppl have mentioned. This belt, in the XL-XXL size, laid flat, completely unstretched is 34.5 inches. If you are kind of in between sizes or on the cusp and want it snug (esp if not using belt loops) I recommend going down a size. I'm a size 14+ pants. I KNEW I was an XL - wasn't sure if I should go L-XL (&risk it being too tight and pulling on clothing) or go to the XL-XXL. The smaller one will be better - thank goodness for free returns for prime members. So far I like this belt, I plan to keep it in my "travel bag" so that I always have a (compact!) belt ready to go that will work for either pants with belt loops, or to dress up/cinch in a dress or skirt/top.
