Boden, Jigsaw, White Stuff, Fatface etc for all the cost/quality reasons above
Gap - because they massively reduced their Tall range
John Lewis - because they closed my nearest branch, which was still a bit of a hike away, but worth it, with other jobs to do in Sheffield.
Warehouse - lost their edge
Racing Green (showing my age here), Kew (budget spin off of Jigsaw) - closed
H&M - the dc too big for their kids/youth ranges, I don't trust/understand their adult sizing
Zara - in fact never did buy anything from them, before a member of floor staff was so rude to me, I left and never stepped foot in again.
Everywhere that sells flipping flouncy tiered dresses - I'm not a flaming milkmaid.
Skinny jeans/trousers of any sort - I have very big calf muscles, partly genes, partly a youth of swimming and cycling
, and have never been able to get skinny trews to fit.
I'm actually having a lot of trouble buying new clothes at the moment.
