A little tip from the former attic dressing room owner:
Don't forget doors on the wardrobes or provide UV protection for the roof windows.
Otherwise, you very quickly get very distinct faded lines on the folded shirts and sweaters^^
We had a lot of clothes lying open (looked great^^) and the sunlight caused excessive fading on the exposed spots. Recognizable as a horizontal line on the folded shirt, as a lighter sleeve on many shirts, and as a light vertical line on many pant legs.
