I'm selling this item because the size didn't fit, although I purchased it and washed it once. It has been washed once and only tried on. The following is quoted from the official website: This is an innerwear with built-in cups that has a moderate thickness and can be worn on its own. The cotton is organic cotton. 【Material】 This material has a high cotton content but is also stretchy. It suppresses the stiffness compared to the previous season's material and achieves a smooth feel against the skin. 【Design】 The neckline is moderately closed, so it can be worn as an inner layer or on its own without looking out of place. The ribbed fabric fits the body well, and the straps are not too thin, so they cover the figure. The length of the hem allows it to be tucked in. 【Specifications】 Transparency: None Elasticity: Yes Fit: Regular
