It is best to have two pairs of bottoms (pants, shorts, or skirts) for each week that you'll be staying. Plan on bringing four shirts per week, and two jackets to layer for warmth (if you're traveling to a cool or cold destination). For a two-week trip, you need four bottoms and eight tops.

For a standard trip, most travel experts recommend the "5-4-3-2-1" packing method to ensure you have enough variety without overpacking. This involves packing 5 tops, 4 bottoms, 3 pairs of shoes, 2 dresses or layers, and 1 accessory set. By choosing a cohesive "capsule wardrobe" where every top matches every bottom, these 15 items can create over 20 unique outfits, which is more than enough for a 10-to-14-day vacation. If your trip is shorter, such as a 5-day getaway, you can scale this down to the "3-2-1" rule (3 tops, 2 bottoms, 1 extra layer). The key is to focus on versatile, wrinkle-resistant fabrics and to plan for one "laundry day" if you are traveling for more than a week. By packing by "outfit components" rather than "one outfit per day," you save significant luggage space and ensure you are prepared for both casual sightseeing and formal dinners without the stress of an overweight suitcase.
