Add a hint of romance to your everyday tank with the Gemma Flutter Tank from Nation LTD. The arm holes are finished with dainty, girly ruffles, effortlessly elevating this top. Why Clean? This top is a blend of linen and pima cotton. Linen comes from the flax plant, which is pesticide and fertilizer free, uses hardly any water to grow and absorbs significantly more CO2 from the air than other crops.
