The Couture Ultimates range have a unique and revolutionary ladder-proof and seamless construction. While traditional hosiery is knitted in tubes made of horizontal rows, the Couture Ultimates are made with vertical lines in one piece with no body seam. This makes them 100% ladder proof (not just ladder resistant) with leg shaping and light control. It's a unique process, making them unlike any other product on the market. The Catherine tights are classic and distinctive opaques with a versatile geometric pattern.
