The Sudoku packing method
Three tops, three bottoms, three layers. Lay nine pieces out in a grid and see every outfit before anything goes in the suitcase.

The idea behind the grid
The 3×3 method groups nine garments into three tops, three bottoms and three layers. Choose pieces that share colors and suit the same weather, so any top works with any bottom, and any layer goes over both.
The grid above is built for a summer city trip. White, black and blue make the base. The layers are a navy blazer for travel, an ivory cardigan for cool mornings and a suede bomber for evenings.
You may also see an older 4×4 wardrobe Sudoku. It puts sixteen pieces, including shoes and accessories, in a grid where each row, column and diagonal is an outfit. It is a different layout with a different count.
What “27 outfits” actually means
That is 27 combinations, plus nine more on days warm enough to skip the layer. Try them on: a bulky sleeve may not fit under a blazer, and some pairings you just won’t love.
Keep the looks you like and swap the piece that leaves you stuck. Your itinerary decides how many outfits you need.
From the grid to a look
Every piece in the grid gets worn, most of them twice. Three pairs of shoes and two bags change with the occasion.
Blazer, crisp shirt and black jeans. The blazer carries the outfit on the plane and comes off when you land somewhere warm.
No layer needed on a hot afternoon. The same shirt from the travel day, now with striped shorts and sneakers you can walk in.
The gingham top brings the color; ivory and white keep it soft. The cardigan covers air-conditioned rooms and comes off outside.
The cardigan buttoned loosely over the strapless top for a breezy morning. The shorts and woven bag keep it casual.
The travel blazer again, now over the gingham top and white trousers. Heeled sandals and hoops make it an evening look.
The black jeans return, dressed up with a strapless top, heeled sandals and hoops. The suede bomber is for the walk home.
Build a grid from your own closet
Travel, walking, work, dinners, and special events. Check the forecast and dress codes before picking a formula.
Decide what you can walk in, then find three bottoms, three tops, and three layers that feel right with them. In real heat, make the layers light: a cardigan or a shirt, not three jackets.
Check proportions, coverage, comfort, and whether the layers fit over the tops. Take a photo of the looks you like so the grid becomes decisions you can return to.
Use Be Well Packed to build your chosen looks for each day and event, then pack from the pieces they use. Add essentials, a laundry plan, and any specialist clothing.
A way to choose a small travel wardrobe that mixes together. Pick three tops, three bottoms and three layers in colors that work with each other, then lay them out in a 3×3 grid. Any top with any bottom, with or without a layer, should make an outfit.
Three tops × three bottoms × three layers is 27 combinations, and nine more if you skip the layer. Not every one will be a favorite, so try them on and keep the looks you would actually wear. Most trips need far fewer than 27.
No. The nine are clothes only. The example on this page adds three pairs of shoes, two bags and a pair of hoops. Underwear, sleepwear, swimwear and toiletries are extra too. Count what you wear on the plane as part of the nine.
No. The older 4×4 wardrobe Sudoku arranges sixteen pieces, including shoes and accessories, so that each row, column and diagonal makes an outfit. The 3×3 version uses nine garments in three categories.
Add the nine pieces you are considering, then build the outfits you want beside each day or event in your Plan. Your planned outfits become one packing list. Be Well Packed does not draw the grid or generate all 27 combinations for you.
