MANILA, Philippines - Preview celebrates its 15th year by giving a lucky reader the chance to win a Chanel 2.55 bag. Designed by Coco Chanel herself in 1955, hence the name, this classic flap bag is one of the fashion world’s most covetable status symbols. To join, readers must text a unique code found in every copy of Preview’s August issue. Each unique code can be used only once. The more Preview copies a reader buys, the greater chances of winning. Read up on the promo’s complete mechanics in the this month’s issue with Andie Eigenmann on the cover, available in newsstands and bookstores nationwide. Promo period ends on Aug. 31.
