Picture this: you get invited to a friend's wedding, book your ticket, snag a hotel room and order the gift. Those three purchases may already make a dent in your wallet - and yet, you still have to figure out what to wear. Finding a spring wedding guest dress may feel daunting, but it certainly doesn't have to be. Depending on the dress code, you might want to consider a cocktail dress. They're a wonderful semi-formal option that will take you from the ceremony to the dance floor with effortless ease.
