I purchased a different belt in store prior to buying this one online. When trying on the in store belt, the mediums were too big & small fit perfectly. So when ordering this belt online, i ordered a small. When it came in, I was disappointed that it doesn't fit the same as the others I tried on in store. Its TOO small. Apparently I should've went with a medium. I just assumed the size chart was the same across the board so i honestly didn't double check before purchasing. So just make sure you measure yourself & check size charts before ordering online.
