This classic, all-American look is easily translated in the bedroom with bold navy blue curtains, pastel green roller shades and pops of bright, preppy color and pattern throughout.

A dark room can help promote better and longer sleep, but doesn't have to sacrifice style. Room-darkening roller shades in bright, pastel hues are a great way to add a pop of chic style and function to your window treatment design.

Preppy style is all about color and pattern. A metallic curtain rod and navy blue curtains lined in a bold, white Greek key add just the right amount of prep to this window. Designer Tip: Hang curtains at the ceiling to make your room look and feel more spacious.

Another staple of classic preppy design? Pops of hot pink, of course! Incorporate this fun hue in small accent elements like finials, throw pillows and side tables.
