The freedom that comes with customized clothing is far greater than readymade clothes. One can choose the design, the color of the cloth and the fabric material to begin with. Women will probably realize this and relate to this better than men when it comes to this.
With the rise in demands, brand loyalty hardly exists. Big names in the market are doing everything they can to retain their customers, customized clothing is a direct result of this quest. Anyone can design the clothes they want to wear and companies will weave it into reality and deliver it to you. This means the control lies in the hands of the buyer and companies can no longer simply force their product in the market. A big chunk of the demand is for customized womens clothes.
