Good, but bad smell
It is lovely except for the terrible scent that is slowly fading over the weeks. It is truly terrible. Not sure if it would be resolved if I washed it.

The comforter is just the right weight for me, looks to be good quality fabric and made well. It rustles when I move in bed, but that isn’t a con for me.
