The front is lace, and the back is a cut-and-sew material. The lace has a lining of the same color, so you can wear it without worrying about transparency. The cut-and-sew material on the back is a smooth, high-quality fabric. The armholes are a bit large, so you might feel more secure wearing something underneath. I think this is a piece that you can wear elegantly and neatly. The color is an easy-to-match off-white, like a milky tea color. After purchasing, I removed the tag and washed it, intending to wear it, but it's unused. For those who understand. Size 11 Length: Approximately 57 cm Width: Approximately 48 cm
