A striped cardigan over a white top and blue jeans is a dependable casual formula. For a more tailored feel, add a light jacket over a simple base and dark denim. A darker blazer with soft wide-leg trousers gives the same layered idea a slightly dressier finish.

Keep the foundation simple: one clean top, a comfortable trouser shape, and an outer layer that adds structure. Loafers, low heels, or simple sneakers can shift the mood without requiring a full outfit change.

These combinations work for commuting, coffee, travel, or a casual workday. The jackets can also be worn over dresses, while the jeans and trousers pair easily with knitwear already in a capsule wardrobe.
