How to pack for a 21-day trip in a carry-on…The 5-4-3-2-1 packing formula that actually works! Maybe you’ve seen the 5-4-3-2-1 packing method trending on your Instagram feed—and honestly, it couldn’t be easier. You pick the items, the numbers stay the same. Here’s my version: 5 tops 4 bottoms 3 pairs of shoes 2 outer layers 1 dress That’s it! These 15 pieces = 21 outfit combinations—one for every single day of a 3-week trip. No overpacking. No “just in case” items. Tons of versatility and lots of options, and it all fits in my carry-on suitcase! Of course, my travel capsule wardrobe rules still apply: – Start with your shoes (2 pairs… okay, 3 max) – Each top works with every bottom, and vice versa – If an item doesn’t work in at least 2 outfits, it doesn’t come on the trip. Pro-Tip 1: For a shorter trip, try the 4-3-2-1 method. Pro Tip 2: Eliminate that 3rd pair of shoes…if you dare! Packing doesn’t have to be stressful, and it doesn’t get easier than this. Get creative with your items. I’d love to know how you plan your 5-4-3-2-1 travel capsule and how many outfit combinations you come up with!
