Jennifer Aniston wanted to add some excitement to her fashion choices for the approaching summer months. She was seen wearing a tube top while shopping at ‘Fred Leighton Rare Collectible Jewels’ in New York City before heading off to the Metropolitan Museum of Art. In contrast to Katie Holmes’ preference for pegged jeans, Jennifer chose a laid-back look with baggy jeans. John Mayer, Jennifer’s former beau, was also seen on Thursday savoring his favorite Japanese cuisine at Nobu Next Door.
