This thread is fascinating, even to see how much our tastes differ. I love those Little Lies clothes but I'm not young or slim. I know I wouldn't look ok in them but I love them. I also love some of the Toast clothing, but I think they only work on certain people. I'm not one of them.
I'm in my 50s and a bit overweight. My wardrobe is mostly M&S, Me & Em (sale stuff), occasional bits from Cos, Baukjen, & Other stories (great for accessories), White Company (sale stuff), Uniqlo, Whistles. A few bits from Primark. And over the last couple of years I'm made some surprisingly good purchases from Tu at Sainsbury's. Really nice stuff.
I never find anything I like in Joules, Fat Face, White Stuff. I'm not sure what their target market is but it doesn't feel like me.
I miss Top Shop.
