Roll, don't fold
Rolling clothes saves space and reduces wrinkles for most fabrics. Pack heavier items at the bottom of the suitcase, near the wheels.
The 5-4-3-2-1 rule
For a week-long trip: five tops, four bottoms, three pairs of shoes, two layers, one hat. Everything should mix and match — if an item only works with one outfit, leave it.
Keep essentials accessible
Medications, chargers, documents, and a change of clothes go in your personal item, never in checked luggage. Assume your checked bag might take a detour.
