There is no doubt that if this coat had proper drape in it it would look better.
So, only thin people can wear drape. Another myth busted.

I was told, about 50 years ago, better drape isn't right next to the scye.
When drape was popular there were tailors in nearly every town, not to mention the big cities. They each had their own opinions about drape. Today we only hear or read about .0000001% about what drape is. I'd like to hear the other opinions, but I can't raise people from the dead to learn more.
Country tailors were know for making loose coats for outdoor work. The Swedes were know for making another type of loose coat. Neither of these two were know as or considered as drape. What other kinds of loose coats are there? From my memories of years gone by what some are calling drape is hardly drape at all. What I saw as a boy is basically the end of the many varitations of drape. The few today is rather simply and not much to look at. Some that was in the past was rather zaney.
There were standards for clothes, which is like rtw, everybody looks the same wearing it. Who wants to be a robot? In the old days some customers competed wtih other customers bringing their ideas to the tailors. Customer and tailor work out the details and then the customer goes and show his friends, each trying to out do the others. Even manufactures were hard at work with new ideas. Todays world where people in their 20s to 30s are discovering tailoring and know nothing of its past seem so timid about stepping away from the herd, it is like looking at stale bread- not very tasty. Strangely, so many "tailoring houses" today are like manufactures with their "house style"- are they really tailors or just better manufactures? House styles are fine, but if they can't depart it how can they be real tailors. Even cheap manufactureing companies change "house Style" every so many months. How is it that those who are supposed to be best don't know how to do something different? Or, refuse? Perhaps another myth is that some of these manufactures are tailors.
