You are not imagining it and you are not being nostalgic. A jumper that would once have been lambswool is acrylic with a lambswool feel. A blouse that looks like silk is polyester that will hold heat and pill within a season. The price has not fallen to match. Only the cloth has.
The Fabric Masterclass
The most useful skill in a shop today is not an eye for style. It is being able to read a fabric with your hands and know, before you reach the till, whether it will survive a year.
Delivered as a PDF the moment you buy. Yours to keep, and to return to.
All sales are final.
Learn this and you will never be sold polyester at a silk price again. It is the single most practical thing I know, and it pays for itself the first time you put something back on the rail.
