Queen size Grey And White Duvet Set

I was gifted this for Christmas this year it’s in great condition just doesn’t match my room anymore.

Dark grey duvet and two pillowcases are from the brand MM Studio( I believe it was bought at bed bath and beyond) The light grey two pillow cases and flat sheet are Calvin Klein.

UPDATE: I’ve also added a white flat sheet and two white pillow cases

From a smoke free and pet free home Would prefer that it goes as a complete set but it’s alright if it doesn’t :)
