I'm not allergic to metals but bought this belt for its simplicity and versatility. I've been wearing it for over a week now and so far I'm loving it. The belt is about 1/8 inch thick and appears to be of very good quality and I expect it will last much longer than my last dirty belt. Your actual waist size. My waist is about 32" and I ordered 34" and the belt fits quite well but there isn't much sagging. It depends on how much sag you want for your style, but I would definitely recommend ordering at least 1 size larger than your measurement.
