Make a list of all the items you will need based on your itinerary. Be realistic about what you need. You don’t need half your wardrobe for one week away.
Instead, you probably need only three bottoms and five tops, or four tops and a dress, where you can mix and match.
Substitute a pair of pants with one or two bathing suits if you are heading somewhere with a beach, or pack a light jacket if you are going somewhere cold.
