For a one-week trip in 2026, the "Golden Rule" of packing is to bring three pairs of pants (trousers). This typically includes one pair of versatile jeans, one pair of chinos or slacks for nicer dinners, and one pair of comfortable leggings or joggers for travel days or relaxing. This 3-pair system allows you to rotate your outfits easily; since pants are heavy and bulky, they are the primary cause of overpacked suitcases. You can wear each pair at least twice (or more if they are high-quality denim or technical fabrics). If you are heading to a very hot climate, you might swap one pair of pants for two pairs of shorts. A peer-to-peer "pro-tip" for 2026 is to wear your heaviest pair (like jeans or boots) on the plane to save weight and space in your carry-on. By sticking to a neutral color palette (navy, black, or tan), you can mix and match these three pairs with 5–7 shirts to create a fresh look for every day of your seven-day vacation without ever needing a laundry stop.
