Most of the tailor shops in here do not have a catalogue. However, there are many tailors in the rich neighbourhood and they have a catalogue where many different designs could be found. They use catalogues in order to guide and facilitate their customers.
How is it possible that the tailor shop in your location doesn't have a catalogue because I find it very difficult to understand how they are going to be able to know the designs they are going to be sewing for their customers. It is from the catalogue that customers choose what they want, how are they going to know exactly what their customer request for them to do without the catalogue?
