Barbie collector Jian Yang stands on a stool as he arranges part of his collection at his home in Singapore September 2, 2013. The white exterior and spartan grey staircase of Jian Yang's tidy rowhouse gives no hint of what lies within - a pink living room floor and his collection of more than 6,000 Barbie dolls. The 33-year-old Singaporean favors minimalist decor but the Barbies and 3,000 dolls of other kinds dominate three sides of the main room and spill over to fill nine mirrored cabinets in his dressing room and the shelves of his study.
