A vanity case is a make up bag with structure, and it is the one I pack when a trip involves more than one look. RIES The Essential Travel Vanity Bag is made with recycled vegan leather and a wipeable satin lining. Emi Jay On The Way Vanity Case in Toasted Sugar is sleek and structured, with a spacious interior for accessories, skin care or makeup. Belletto The Essentials Clutch is my favorite idea in the row: it holds a whole skin care routine upright, so every bottle is visible when you unzip it.

CALPAK grew from soft duffels into hard-sided luggage, and its clear cosmetics cases carry that thinking into the bathroom. The Medium Clear Cosmetics Case in Glazed Dark Cherry is the best-selling size, compact enough for a carry-on. The Small Clear Cosmetics Case in Mushroom has two compartments and a water-resistant lining, and the Clear Train Case with Top Compartment in Celadon is the one for a full kit, with transparent panels and a zip-around opening. OLIVE YOUNG Collection Daily Beauty Organizer is a structured pouch in ivory and navy that works just as well on a vanity at home.

A packing tip: stand liquids upright in the case, then fill the gaps with sticks and pencils so nothing shifts in transit.

What I would skip: a big train case for a weekend away. The small clear case holds a full face if you edit down to sticks.

Sticks are what make a small bag possible, because one stick can do the work of a palette and a brush. Westman Atelier has three here, all from makeup artist Gucci Westman. Baby Cheeks Blush Stick in Bichette is a multi-use cream for cheeks and lips, Lit Up Highlight Stick in Nectar is a barely there gel highlighter, and Face Trace Contour Stick in Biscuit has taupe undertones and a velvety texture that will not interfere with the makeup underneath. Kosas Impressionist Multistick in Surreal is another cheek and lip stick, with CoQ10 and a conditioning botanical complex.

Jillian Dempsey Spot Stick Concealer in No. 01 is the one I would never leave behind. Dempsey made it to mimic her own technique for erasing discoloration on clients, with dense pigment and vitamin E. Victoria Beckham Beauty Posh Balm in Glace gives the plush shine of a gloss with the wear of a balm, so there is no sticky tube to leak in the bag.

The last two are for people who want the bag to look as good as what is in it. La bouche rouge makes refillable leather cases, and here are its compact case and lipstick case, both in camel.

A small-bag test: if your kit fits in the CALPAK Tiny Clear Case, you have edited well.

What I would skip: loose powder in a soft pouch. It always finds a way out, so choose a pressed or stick formula for the bag.

Once a month, empty the bag completely, throw out anything that has separated or changed smell, and sharpen your pencils. Wipe a leather or coated lining with a damp cloth, and spot-clean a cotton pouch gently, letting it dry fully before you refill it. Keep brushes in their own pocket so powder does not coat everything else. Liquids travel upright, and anything with a cap that clicks shut is the safer choice for a trip. A make up bag that zips closed easily is one you have actually edited, and it makes getting ready anywhere faster.
