I know someone who has worked in QA for a high street shop (mentioned in one or two previous post)
This person knows her clothes as she worked in the industry (worked for a designer as a seamstress/tailoress). She likes all sorts of brands and not necessarily ones you'd think of.
If I got this right:
A surprising one she likes is Bon Marche. (yes, I know, but she says they make comfortable trousers)
On the quite happy to wear are things like Fat Face, Joules, Boden, M&S and Jaeger (from a few years ago), House of Bruar and Peter Hahn for knitwear, Hotter, Skechers, Rohde for shoes
She really likes Toast and SeaSalt, and says their quality is great, after that the more top end brands like Aquascutum & co. Due to age and Covid she does buy from mail order but not internet.
Bear in mind that this person is retired and has been for about 10 years so her taste is not a 35-yr old's but she dresses quite 'young' for her age.
One thing she has said is that standards hove gone down noticeably, not just in clothes but in things like dressmaking fabric and knitting yarrn.
