Reese Witherspoon traded her skimpy two-piece for a black suit with a plunging neckline in Hawaii today. She headed to the water with Ava, Deacon, shirtless Jim Toth, and another group of pals during their latest outing. The whole crew took a dip in the ocean before Reese and Jim shared a sweet moment on the sand. We've seen a lot of Reese Witherspoon in a bikini during the family's getaway to Kauai, though Reese covered up for a sunny lunch on Wednesday. Reese and Jim took Ava and Deacon to Bubba Burgers, as they continued their island trip as a foursome.
