Q.5 Mr. Peter D’souza has a chain of restaurants in many cities of western India and was interested in diversifying his business. His only son, Ronald, decided to venture into garment manufacturing. Ronald had already done a course in fashion designing and wanted to do something different for the consumers of this industry. An idea struck him that he should design garments for ladies who are very bulky but want a lean back look after wearing readymade garments. The first thing that came to his mind was to have an estimate of ladies who wore large sized dresses (40 size and above).
An experts meeting was called containing brilliant people from the garment industry and a number of fashion designers to discuss on how they should proceed. A common concern for many of them was to know the size of such a market:-Another issue that was bothering them was how to approach, the respondents. It was believed that asking people about the size of their dress may put them off and there may not be any worthwhile response.
