I used this item five times after purchasing it, but I am selling it because I need a different size. I will add photos. The seventh photo indicates a vertical size of 28, but this model is a size 26 cm. When worn, I wore a shirt underneath. It has been home-cleaned. Purchased from an online store (around March). As shown in the photos, there are some areas with rough stitching from the time of purchase, and some of the wire is visible. I think it can be fixed by hand-sewing. It's mesh, so it should be comfortable to wear. [Brand] Burvogue [Color] Beige [Size] M [Material] 100% Polyester [Product Details] This waist nipper corset is made with attention to detail in every aspect, including the material, sewing, comfort, elasticity, and durability. The main material, polyester, is a material often used in the clothes people usually wear, so the possibility of skin problems is extremely low, and the material is thin, so you can wear it comfortably. With 9 spiral steel bones and 14 rows of 4 hooks, it can be adjusted to fit your body condition. If you gain excess fat around your abdomen, the fit of the waist area will be lost. It firmly holds your stomach and creates a beautiful waistline. Because it uses thin fabric, it doesn't expand when worn and is comfortable to wear. It tightens your stomach with appropriate pressure, has a good waist-cinching effect, and improves your posture. It maintains a beautiful posture even when sitting, and the posture effect is remarkable. People who have problems such as back pain from sitting for long periods of time can also wear it with peace of mind. In addition to a cinched waist, it also straightens your back and improves slouching. The mesh fabric has excellent elasticity, so you can spend long hours wearing it comfortably.
