I just watched a Youtube Video by The Fold Line which recommended
this link. It goes to a 1967 BBC programme called Clothes That Count | Shirt Waister, where a women shows you how to sew a 'Shirt Waister' (what I would now just refer to as a shirt dress).
I never realised that the BBC ever had programmes like this. I thought it was interesting that the dress was something I could see myself wearing today (though probably not styled the same way). It's interesting to see how sewing has and hasn't changed since the 60s. She gives tips that people still follow to this day (such as doing one diagonal stitch on a corner), and also mentions things that I would take for granted (like being able to back stitch on your machine). She does a lot of tacking too, which I always try to do but it's never been ingrained in me.
They talk about the difference between cheaper and more expensive patterns. Things like moving towards printed patterns rather than punch holes, seam lines, different variations and instructions. That's interesting to me because with the boom of indie patterns the pricing of a pattern has changed and is more dependent on the company and not necessarily value for money.
There's some more links on the right hand side that I haven't watched yet. As part of this series there's episodes on the suit and a double breasted coat. One other thing I want to watch is from the 50s and about how fashion comes and goes.
If you don't watch the entirety of it, I do recommend watching between around 19:30~21:30 for the fashion show. I wont tell you why, but I promise it's worth it.
