Emily Mariko's Must-Have Products, From Diptyque to Linen Sheets

Mariko depends on her Tumi International Expandable 4 Wheeled Carry-On ($750) for all her travel needs, including fitting about a week's worth of clothes.

"This is the first suitcase that I've found with this interesting closing mechanism. It has two buckles or clasps that close the two halves together instead of a zipper, and that makes a huge difference in terms of how much you can stuff this thing," she says. This suitcase also features a zipper expansion, four spinner wheels, and a built-in USB port.

Pro Tip: Mariko loves traveling with compression socks to make her journey more comfortable.
