Choose a soft first layer
A fine rib top creates a simple base under a cardigan. Compare the fit of both pieces together if you expect to wear them as a pair.
Change one proportion at a time
Pair a closer top with a looser lower half, or reverse that balance. This makes the outline easier to read without requiring more pieces.
Finish for the actual route
Consider walking distance and what you need to carry. Choose footwear by its confirmed measurements and your own comfort, then select a bag that fits the items you will take.
