I love these on you. I was biting my nails waiting for a picture!
Not even in the same stratosphere, but Old Navy had a pair of similar, but obviously not as luxurious, pants in their loungewear section last week. I bought a pair and instantly thought I could live in them. i went back after seeing your post so I could share a link for anyone who might want a cheap test drive version, and they're totally gone. They were called "harem-style cropped pants". The crotch is probably a bit higher and they don't have the pleating action yours do. I hope they come back, I'd probably buy 3 more pairs. I'm afraid I'm going to wear these out too soon because they're so comfy for lounging around the house in, but the new shape is refreshing and makes me want to wear them every day.
