A useful wardrobe is not a fixed number of pieces or a shopping list. It is a small collection of clothes that works for the life you actually lead. Begin by noticing what you wear over two ordinary weeks: your commute, work, weekends and the weather all matter more than an idealised version of your routine.
Start with what you own
Lay out the pieces you reach for most. Note the shapes, colours and fabrics you enjoy, then identify what makes the less-worn items difficult. A missing layer, uncomfortable waist or dry-clean-only label can tell you more than a trend report. Keep clothes that fit your current life and set aside anything that needs repair or alteration.
Build combinations, not a uniform
Choose a few compatible colours and create outfits around actual activities. A jacket that works with two pairs of trousers and a skirt is more useful than one that only works with a single look. Add personality with a favourite texture, a bright shirt or jewellery: a capsule need not be beige.
Fill a genuine gap
Before buying, write down at least three ways to wear the item and check its care label. Extending the use of existing clothes is a central idea in the Ellen MacArthur Foundation’s work on circular fashion. Treat the wardrobe as a living edit: review it seasonally, repair what you can, and let your preferences change.
