If you've got a few collared, button-down tops that you usually save for the office, you can easily transition them to weekend-wear with one simple trick - tie a knot in the middle of 'em! Fashion the top few buttons to keep your cleavage (mostly) out of sight, and knot the loose shirttails around your bellybutton. You'll show off just a hint of your tummy, but you'll still look laid-back and fashionable.

Summertime is also the perfect opportunity to rock a hat. Always dreamed of wearing a massive-brimmed Kentucky Derby-style hat? Now's the time! Sport one for a day at the beach or just wear it during your errands - you're sure to get noticed.

Wedges are another easy summer staple. The perfect marriage of casual and elegant, they'll give you the lift of a pair of heels without the discomfort. Go for a strappy look to show off your pedicure.
