Gray sleeveless top, size M, made of 100% polyester. - Sleeveless innerwear Color: Silver Silhouette: Sleeveless Material: Polyester Length: 53 cm This innerwear feels smooth and comfortable. I've used it as an inner layer for jackets, and it worked well in formal settings. It has been cleaned after use, but has been stored at home for many years. Please refrain from purchasing if you are concerned as it is a used item.
