It fits pretty tight but it works with longer shirts

Maybe the picture makes me think it'll be bigger but it's only about 12" long. It stretches but I'm 6'2" and wear 34/34 pants. If I was wearing a longer dress shirt it worked fine but if I wore a dress shirt that didn't hang past my torso it was way too tight to wear. I tried it with a few shirts and then stopped wearing it. If the elastic side was 6" longer I think it would fit much better.
