The two show off their slim figures and amazing fashion sense.  While Krystal went for a more trendy and modernized business casual look with a blue blouse and subtly patterned pants, Jessica went for a more edgy fashion with a crop top and tight leather pants! In the Instagram photo, they are seen posing with Jimmy Choo's creative director Sandra Choi.

This just proves their gene pool gifted them with both good looks and a great sense of style, but whose outfit do you personally like better?
