I purchased this, but it's unused and still sealed. Light Gray Size L From the purchase site: The lace is a mere 0.6 millimeters thin. Furthermore, the surface that touches the skin is a blend of naturally derived cupro, so you don't have to worry about the scratchiness often associated with synthetic lace. The lace is heat-bonded, so there are no seams. You're unlikely to find another seamless bra with such thin fabric and a cupro blend on the skin side. Cupro, which has excellent absorbency, absorbs sweat, providing 2.5 times the sweat absorption of cotton. The lace allows 6 times more air to pass through than cotton knit fabric, so both the underbust area, where sweat tends to accumulate, and the back, which is prone to stuffiness, stay dry. The padding material has air holes, so you don't have to worry about stuffiness around the bust. Retail price: 3960 yen
