Part of the reason Maarten De Ceulaer's 'A Pile of Suitcases' wardrobe is making such waves at Dutch Design Week is its inherent simplicity.
After all, isn't a packed suitcase essentially an All-Star roster of your closet? All of the pieces are appropriate for the season, fit you well, are versatile, generally wrinkle-free and easily-laundered, and are items you love to wear. No one departs for a trip to Aruba with a suitcase full of clothes they hate. Maarten De Ceulaer's wardrobe design is quite appropriate in this regard.
Perhaps a wardrobe like Maarten De Ceulaer's 'A Pile of Suitcases' would force you to think of your closet the same way you would your suitcase, tossing clothes that you don't like and packing away clothes that are inappropriate for the season.
