Do the clothing countdown: If you need a mantra to help streamline your wardrobe, use the 5, 4, 3, 2, 1 rule for a weeklong trip: Limit yourself to no more than five sets of socks and underwear, four tops, three bottoms, two pairs of shoes and one hat. The list should be adjusted to suit your needs.

For a long-term trip, the most effective strategy is the "Rule of One Week": pack enough clothes for 7 to 8 days, regardless of whether you will be gone for two weeks or two months. This approach forces you to rely on laundry facilities while keeping your luggage manageable and lightweight. A standard "capsule wardrobe" for long trips typically includes 5–7 tops, 2–3 pairs of pants or skirts, 1–2 sets of sleepwear, and enough undergarments for the week. By choosing items in a consistent color palette, you can mix and match to create dozens of unique outfits without overpacking. Additionally, layering is key for unpredictable weather; a single high-quality, lightweight jacket or a versatile cardigan is more efficient than several bulky sweaters. The goal is to maximize the utility of every item so that your bag remains easy to carry across cobblestones, up metro stairs, and through crowded airports.
