Trouser construction Extended | Guide to a Bespoke Suit 

Thanks, but I might suggest the more recent one of these I made is a bit better.

I don't really understand the question. Is there a certain cut/silhouette to TF and DG trousers that you are looking to replicate? Or a construction method, or just the features of the trouser. Like a particular shape of the side strap. If it's the shape and you wanted to replicate that, then since we don't know How the patterns are drafted then yes, I think you could try taking the measurements from a TF trouser.

@@caffeinatedtailor Hi, thanks for your reply.Let's say you took the measurements from a person to make a jacket and you draw on a piece of paper according to th a pattern you found on a book. You would like to modifiy the form of the lapel.Instead of the notched lapel you would like a shawl lapel or one of your own design or you would like to imitate one of a TF jacket..How would you do that on the piece of paper? First question Suppose now, you have a client who do fitness and who have huge back muscles and you need to add some space in the back how would you do that in the piece of paper where you put the measurements? second question Hope it's more clear now. Thanks

Thank you the clarification helps. The second question is more difficult for me because I don't have much/any training in fitting at the moment. Though I am aware that Savile Row Tales and Tom Mahon are actively working on a fitting series. Ideally that will help us all with fitting patterns. First question, when your initial pattern is fitted and you know it's correct at that point you can start playing with it. It's mostly a case of preference or what you think is best. At the moment, I prefer to copy the pattern onto new paper to keep the original and make the new shape and design. I'm aware Redmayne prefer to have the one pattern and change it on the cloth, but they make rather common changes. That's about as much as I can communicate. I hope it adds some clarity at least.

Probably not, but it must do something. You want to avoid getting lining wet at all. Steam is fine, but water won't come off. It's only canvas that is generally suggested to be soaked.

I'd venture that buttons were the classic option since they're older.

Cloth soap, or tailors soap if you like. I elaborate on its use in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cNiBZ6g3NMQ.html (Setting the fabric)
