Or do what we do...
All bedding, sheets, pillow cases, and towels, are white.
We only put a cover on the duvet for visitors. For ourselves, we just have a top sheet between us and the duvet, no cover on the duvet.
All our duvets are white ‘peach skin’ material and look like they’re not meant to have a cover on.
Did away with duvet covers for ourselves about five or six years ago, it’s saved so much stress and struggle.
