A cami—or camisole- is a sleeveless shirt normally made of linen, cotton or sheer satin and is worn as underwear. It can extend to the waist or be cropped. Once worn under shirts, blouses and sweaters, it has now emerged as a summer staple, worn on its own. A cami is pretty when worn with a skirt or a pair of shorts and coming in all colors, patterns and materials, there is no reason not to have at least one in our closets. A look at Tumblr shows how fashionistas can style a cami to look cute or sexy, depending on the look going for and the occasion.
