I know the brands of corsets, such as Wagner, Mei Ting and Manifen. But should the old brands that have been developing for nearly 20 years, namely Amore, Simu and Pure Color Woman, focus on making seamless corsets? All of them are owned by Amore Company, which is the standard-setting unit of seamless corset in China Textile, so it has been making products in the direction of "seamless is comfortable".
