Do you want lingerie that can double as casual or sporty wear? These are perfect for that. In a zipper-lock fashion, you get plenty of opportunities to shift back and forth from wholesome to daring. The zipper starts from the bottom of the butt and traverses through the collar. In a fully zipped-up setup, it would be a rounded neck style. Made of spandex, they are flexible to a point. Because they are long sleeves, they can protect you from the cold weather. They also come in bright color ranges.
