These pants were purchased a few years ago. I've worn them a few times. The waist is elastic, and they're made of thin, soft denim, so they're comfortable to wear even at home! They also have pockets. The color looks white in the photos, but it's actually a light green. The color is most accurate in the third photo. The size is XS, but I usually wear a size M, and they fit perfectly without feeling tight at all. Someone who usually wears XS might find them a little big. Please refrain from purchasing if you are overly concerned about details.
