What: Striped shirt with keyhole neckline

Where: French Connection

Price Tag: $68

Why: There's something so dear about the combination of short puffed sleeves and a peekaboo neckline. It's reminiscent of a 1940s pinup girl, sweet and sexy. The contrasting white piping and big buttons dress this shirt up a bit. It would look especially pretty with a hint of lace peeking through the keyhole, and cute as a bug with a bright T-shirt underneath. Go for fall's biggest beauty trend and splash on red lips for the complete look. This adorable turquoise-and-aqua top also comes in basic black with white stripes.
