Follow the 5-4-3-2-1 packing trick, where you pack five tops, four bottoms, three dresses, three pairs of shoes, two swimsuits, two bags, and one of each of a few miscellaneous accessories. If you're opting for a carry-on, mix and match items in your travel capsule and have a versatile wardrobe.

The secret to packing for a 10-day trip is the "5-4-3-2-1" rule combined with strategic layering. Aim to pack 5 sets of socks and underwear, 4 tops (mix of tees and button-downs), 3 bottoms (jeans, chinos, or skirts), 2 pairs of shoes (one comfortable for walking, one slightly dressier), and 1 accessory like a hat or scarf. To save space, use compression packing cubes to compartmentalize your clothing and prevent it from shifting. Choose a color palette—like navy, grey, and white—so every item can be mixed and matched to create over 10 unique outfits. For a trip of this length, plan to do a small "sink wash" halfway through or use a local laundry service to keep your bag light. Remember to pack a universal travel adapter, a portable power bank, and travel-sized toiletries to comply with the 3-1-1 liquids rule. Packing light (ideally in a carry-on) avoids the stress of lost luggage and makes navigating foreign train stations or cobblestone streets much easier.
