I don’t go in often but when I do it’s first thing in the morning when it’s much quieter.
I’m selective about what I buy. Currently the have some reasonable cotton dresses and tops in styles I like. I try stuff on as sizes are not reliable. They sell more eco-friendly tee shirts that cost more than the cheapies but last a long time.
Underwear; this generally doesn’t fit me well but I have bought sleeveless and sleeved vests, 95% cotton and 5% elastase. These are very good and not surprisingly I’ve seen the same/similar products in both M&S and H&M but more expensive, all made in Asia.
Some programmes have highlighted the fact that many of our brands of clothes are all made in the same place with different labels.
I don’t buy many new clothes and only cotton and wool if I can afford it, otherwise I make do.
Primary is okay, just be selective and shop early.
