Your own personal shopper -- free -- at J. Crew

The phrase "personal shopper" inherently has a certain air of snobbery about it, calling to mind that wealthy aunt who always bought the best Christmas gifts but whose over-the-top get-ups elicited constant eye-rolls from your mother. No more. J. Crew has quietly rolled out services that bring personal shopping to the masses -- by not charging for it.

For guys, there's "Jack Knows Best." Here, male customers can read basic tips on blazers and bowties from a company stylist -- but they can also email him about specific sartorial conundrums at jack@jcrew.com.
