Sudoku packing method: 9 clothes, 27 outfits, no excess baggage

The Sudoku packing method involves selecting 9 clothing items — 3 tops, 3 bottoms and 3 outer layers — that all mix and match with each other. This capsule wardrobe approach yields up to 27 different outfit combinations from just 9 pieces. The method eliminates overpacking and the struggle to close an overstuffed suitcase before a trip.
