Used for a few months, and then stored in linen closet for a long time. Does it look brand new? No, but it doesn't look worn-out either.  This Calvin Klein cotton duvet is super soft and is a thicker cotton than other cotton Calvin Klein duvets I've had.  This duvet seems to wrinkle more than others - I think it's the result of the cotton being super soft; almost like a flannel-feel to it.
