Sisters Jessica and Krystal posed for the November issue of 'Cosmopolitan.'  

Because of their busy schedules, they arrived in New York for the shoot on different days, but when they finally met up, they hugged and looked happy to see each other, once again showing how close they are.  

They were super charismatic and chic during the shoot.  Jessica spoke in fluent English, asking the photographer if she should try switching poses with Krystal or try the shoot from different angles.
