This is made for men who are of medium sizes.It does not adjust for waist size. If you're a woman, a large size might fit. You can go to Home Depot and find a comparable, high quality belt with shoulder straps in multiple sizes for 1/4 for only $14.
The brace came was exactly as stated. I use it daily for my aerobics and it provides great stability. The velcro and elastic are very strong and sturdy. It does a great job as a back brace. I would definitely recommend it to anyone in the market. Also, it came out great from the washer on the normal setting and after being air dried.
