It doesn't matter how big or small your closet is, when you have Weardrobe — your online closet.
Weardrobe lets you upload photos of yourself, which you then tag (i.e., 'Zara trench coat'), and then the website organizes your articles of clothing — trust me, it's better than the Container Store.
You can then maintain the virtual inventory (instead of the actual mess) of your clothes for either deciding what to wear.
