First let me say this runs TRUE TO SIZE!! I am a size four in pants and 5'3"&120 pounds. The 4/6 is PERFECT - not too tight, not too loose. If you want a looser fit then size up! But if you want the fit on the model stay true to your size. Also, check the size chart just to be sure.

The material is lightweight, almost silky feeling. I really like the feel on my body and it is not see-through. It's in fact better quality than I hoped for!

The belt comes separate but there are two belt loops in the front to keep it in place so I didn't really have an issue with it.

Overall, I give these pants 5/5. Absolutely no issues with sizing or quality or fit (they look SO good on). Such a classy, staple piece and comparatively cheap to other department stores. I would 100% recommend this.
