The best trips start with the lightest bag. A travel capsule — a small set of pieces that all work together — means you pack once, wear everything twice, and never check a bag. Here's how to build four complete outfits that fit in one carry-on and come out ready to wear.

Start with wrinkle-free tops

Your tops do the heaviest lifting, so they should be the easiest. Three or four JudyP tops in colors that mix — say two neutrals and two of the new colors — give you the base of every outfit. Because they're wrinkle-free microfiber, they pack flat and pull out crease-free, so you skip the iron entirely.

Add two bottoms and one layer

Two bottoms (a white or neutral pant and a denim) cover everything, and one light jacket handles cool evenings and over-air-conditioned restaurants. That's it — three tops, two bottoms, one jacket already makes six outfits.

Finish with shoes and a bag that go with all of it

One pair of leather slides and one basket or crossbody bag in a neutral will match every top in the capsule. Keep accessories few and neutral and everything multiplies.

Four outfits, one small bag

• Coastal: Capri top + white pant + leather slides.
• Weekend: Sunflower top + denim + a basket bag.
• Evening: Terra Cotta top + neutral pant + a jacket.
• Travel day: any top + the jacket + comfortable slides.

Every piece here layers with every other, so four outfits is really more like eight. And because nothing wrinkles, your carry-on stays light and your mornings stay easy.
