Stretch tube tops

Tube tops are one of those pieces of clothing that is great to own because they are so versatile. They can be worn under a blouse or jacket, but they can also be worn as is, with nothing covering them. However, since they are stretchy, they can be rather unforgiving depending on your body shape. So make sure you are comfortable wearing something skin-tight before you buy.
