The renowned designer - whose celebrity fans include Victoria Beckham, Cameron Diaz and Demi Moore - says he only worries about impressing his costumers with his creations as it's important for them to have confidence with their appearance.
He said: "Women who wear my dresses look good in them. I don't know why my designs have been so successful but women love them and that is very important to me and it's all that matters."
Roland also revealed how he is a huge fan of couture but wouldn't consider launching his own line.
He said: "Couture is still so important to fashion. Watching the world of couture is like being in a family - you don't have to do everything your family does but you can take a lot you can take from them."
"But it is not for me. I prefer ready-to-wear, there is space for both but for me I want to carry on designing my lady dresses."
While he doesn't want a couture line, Roland recently celebrated the launch of his new menswear collection and said it was a new and exciting challenge to create clothes for men.
He said: "The concept of the menswear came around from some of my female customers saying it would be interesting to see what I could do with a man. My notion of a man and a woman is that the woman is the jury and the man is the boss, you don't create the same kind of clothes for men and woman but the two do complement themselves."
