Roy Caires, owner of Alter, peruses the racks

It's hard to stay on top of trends in a city like New York, where a fashion must can become a fashion don't as quickly as a career on Wall Street can fall from grace. You miss the days when mom laid out your skirt and spandex onesie the night before school--when you didn't have to think too much about whether or not a fedora worked with your skinny jeans and vintage tee. Between boozing, eating and sleeping, you barely have time to shop, let alone lend precious time to planning your day-to-day get-up. So skip the needless worry, and trust our expert shop clerks to do the tough work for you this season--from selecting the perfect all-in-one tuxedo at Albertine, to sorting through the racks at Mayle for the best winter coat. Their picks for fall's must-haves are stylish and of-the-moment. And if you need help finding that perfect pair of jeans, we've got that covered too.
