EXCLUSIVELY DESIGNED BY ZTL FOR YOU! Lana took the market everyday set and solved two problems. First, our shirred sleeves allow you to move 360 degrees without having your entire arm show. Second, we added a back invisible zipper to give you a more modest round neck collar that doesn't show your neck and back as you conquer your world! With effortless versatility day or night, it will quickly become part of your everyday wardrobe. The belt is optional so you can style it with or without.
