How do I find a good jacket?

Measuring things like your shoulders and arm length will do wonders for you. Chest measurements can also help, but they're only good for suits that are Off The Rack. Many suits and jackets on eBay are tagged but remember to check the measurements before buying. Think about what style you like, what you'll use your coat for, what level of insulation you want, and what your budget is. "The most important thing is buying something that's good quality and classic, that you feel like could last you a lifetime," says J. Crew Head of Women's and Crewcuts Design Olympia Gayot.
