Love it! Completes my new bedroom set perfectly. Luxuriously smooth fabric, feels very classy. I especially like the stitching pattern, simple yet elegant. Goose down duvet fits well and does not move or become dislodged in the duvet cover. Not sure how it washes yet but I imagine it will not be unlike typical bedding.
UPDATE: Marks remove easily with proper care. It washes well (I do cold water only, normal spin cycle, low heat in dryer). The button closure holes are getting a bit stretched out so the buttons come undone but it's not an awful hassle. My only critique for improvement after over a year of owning these would be that the button holes are reinforced.
