Found this thread from black tie guide and I finally made it through all 234 pages. I diligently read every post up until about page 90, after that I admit I did skip some of the prose to get right to the "porn" of the thread.
Thank you all for posting in this thread. What I like about this thread is that I have an idea of just how much I don't know so I can keep learning. The links and sources along the way have been invaluable. I'm looking forward to exploring the world of fabric in more detail so I have a better appreciation for my wardrobe.
EDIT - now that I think of it I have a question. A few years back (somewhere between page 80 and 90 in the thread) a few people were having a row and someone commented about how someone "grew up from Acorn" to other fabrics. Was this just a jib, or is there a quality issue with them?
