The 3x3 Method: How to Pack One Suitcase for Every Summer Trip

The 3x3 Method: How to Pack One Suitcase for Every Summer Trip

You know the feeling: suitcase open on the bed, five "maybe" outfits laid out, and a nagging sense you're still going to pack too much. We built the 3x3 Summer Travel Edit to end that spiral for good.

The idea is simple. 3 tops, 3 bottoms, 3 layers, and one bonus dress — mixed and matched into more than 27 outfit combinations. One small stack of clothes. A full trip's worth of looks. No black-and-white capsule-wardrobe rules required.

Why 3x3 works

Most "travel capsule" advice defaults to neutrals because neutrals are foolproof — but foolproof doesn't have to mean flat. Our edit builds the whole system around a cerulean blue and warm pink palette, so everything already coordinates before you even start mixing pieces. You get the ease of a capsule wardrobe with the personality of clothes you'd actually pick off the racks.

And because everything is done in linen, cotton, and jersey knits, the fabric works as hard as the color story does — breathable in a hot car or a warm airport, and forgiving after being folded into a packing cube for a week.

The 3 tops

  • Ruched Top in White Waves Jersey — a soft, ruched jersey tank that layers under everything or stands on its own.
  • Neko Tank in Cerulean Stripe — a classic sleeveless stripe that anchors the whole palette.
  • Millie Muscle Tee in Fern Beats Blue — the pattern play that keeps the edit from feeling too matchy.

The 3 bottoms

  • Emma Skirt in Blue Stripe Linen Cotton — an easy linen-cotton skirt for market mornings and dinner out alike.
  • Isla Skirt in Cerulean Slub — organic cotton jersey that packs flat and never wrinkles.
  • Emmy Drawstring Pant in Cerulean Stripe — the comfort piece for travel days, currently on sale.

The 3 layers

  • Fisherman Cardigan in Cerulean Cotton — for chilly flights and breezy evenings.
  • Camp Shirt in Pastel Cacti — the pattern piece that gives the whole edit its "pop of print."
  • Mae Oversized Top in Blue Stripe Linen Cotton — an oversized linen-cotton layer that throws on over any tank or dress.

The bonus dress

Coordinated doesn't mean colorless

Here's the part worth saying out loud: you don't need to pack in black and white to stay coordinated. A tight, intentional color story — like the cerulean blues and warm pinks in this edit — coordinates just as easily and photographs a lot better. Pattern mixing gets easy, too, once every piece is already speaking the same color language: stripe with print, print with solid, solid with stripe.

How to build your 27+ outfits

Think of it as a simple rotation:

top + bottom + layer → layer + top + bottom → bottom + layer + top

Rotate through the 3 tops, 3 bottoms, and 3 layers, and you've already got 27 unique combinations before the dress even comes into play. Add it in for a 28th no-brainer outfit, or wear it layered under the cardigan or camp shirt for versions 29 and beyond.

One small stack of clothes. A suitcase with room to spare. A trip's worth of outfits that still feel like you.
