Taylor Swift exuded retro chic while hanging out with boyfriend Conor Kennedy and his dad, Robert Kennedy Jr., at his family's house in Hyannis, MA. The singer sported a red halter polka-dot bikini top and navy-and-white striped Marc by Marc Jacobs shorts ($104, originally $148) on bottom. Taylor then completed her vintage look by tying a printed bandana around her head and painting her lips red. Before Summer comes to a close, be sure to mimic Taylor's vacation look by pairing a similar polka-dot bikini top with striped shorts.
