You don't need a cottage in the Northeast to imagine the classy Boston aesthetic. From fashion to decor, everything is preppy, polished and luxe - but nothing steals the show quite like boutique-style winter dresses on Newbury Street. Luckily, you don't need a plane ticket to get the look. Our favorite East Coast-inspired dresses are secretly on Amazon, and they start at just $11! Even better, these affordable picks are as flattering as they are stylish.
