Depending on the brands, I normally wear sizes between small or medium. I ordered this in small. It's not loose, it fits me perfectly, I think if I had ordered a medium, it might be more relaxed from the legs, but the length might be longer. I do love the material, it's comfortable to wear.

I ordered these leggings because I liked the colors. They're exactly as shown. The colors are bright and vibrant. I received compliments on these leggings. I ordered a size small because I read that they run on the bigger size. They fit me perfectly. I do think that the leggings are a little tight but they're supposed to be made that way.
