Dreaming of that much-needed summer vacation but already dreading the packing? We asked Zac Posen, whose debut collection for Target hits stores April 25th (this Sunday!), to tell us the secret to chic summer travel. Number one on his packing checklist? “A girl should always travel with an LBD," Posen told us. "Our knit LBD is especially scrumptious and versatile—perfect for a beach holiday!” The line’s versatility also makes it easy to pack light. “The tie-dye tank dress is the perfect cover-up and can be carried from day to night with the right belt." And don't forget the most important piece: “A girl can’t possibly go on a summer getaway without a smokin’ hot bikini! Our gold lurex two-piece is to die for!” If you're in N.Y.C., get a head start on your summer style at the 24-hour Zac Posen for Target pop-up shop in Herald Square—opening tonight at 11 p.m.!
