ZARA BASIC Women's Pants Slacks Color: Blue-gray Size: USA S Although it's a size S, it fit me perfectly, and I usually wear a size M. The back has elastic tape, making them easy to wear. There are slits on both sides of the hem. The material is neither too thick nor too thin, so it doesn't show underwear. Also, they have good stretch, making them easy to move in. Worn a few times and home-cleaned. Thank you for looking.
