The Luisa Top is a softer, more romantic tank, with a loose fit through the body, longer length, and soft drape at the neck. We certainly aren't sacrificing comfort for style on this one, and you won't be either. In efforts of keeping Mother Earth healthy & happy, we chose to use lyocell fibers from TENCEL™ in this material. Lyocell fibers are derived from sustainable wood sources through sustainably managed forests. 5% Spandex for retention and your comfort.
