The quality is good. The size is also as described in the product description.
At this price and with this quality, if you find something you really don't like, then there's a bit of a problem with the design.
Should I say that the leg openings are small or that the hip area is small... Anyway, it's a bit uncomfortable.
It may vary depending on the style you wear, but the indicated waist size is the size when laid flat.
