A virtual wardrobe app digitises your clothes so you can plan outfits from your phone. Our pick is Stylin AI, a free iOS app that not only catalogues each piece by type, colour and style but actively builds outfits from what you own and shows them on your body shape, then fills gaps with shopping picks. It holds a 4.8-star rating from around 500 reviews. Well-known alternatives include Whering and Acloset for cataloguing, and Pureple for outfit planning. The best choice is the one whose styling you actually use daily.
