Prompted by waking up to realise I've had a really grim year and desperately feeling the need for a style reboot, but suddenly feeling quite lost and unsure how to go about it.
For the last few years I've tried to shop more sustainably and better quality. Lots of good quality second hand via ebay, some good quality stuff in the sales. But I've woken up to realise that my wardrobe suddenly feels quite staid and dated. I don't feel the need to be bang on-trend but I do want to look a bit more modern. But I also really hate the idea of buying cheap clothes just to stay vaguely on-trend. I love the idea of buying investment pieces, dressing in really high quality clothes, shopping more ethically, and I hate poor quality fabrics and tailoring, but I still want to feel vaguely stylish and modern. 
Given that fashions do move on, is there any answer to this particular dilemma? Or are there brands that are good quality and sustainable but also fairly stylish and modern, that run that elusive thin line between "classic and good quality but boring and frumpy" and "stylish, modern, affordable, but will rapidly look like last year's fashion and the fabrics are rubbish"? I've just ordered some dresses from Mango and Monki (lower price point than my typical high-end high street via ebay/the sales type purchases) and they do definitely look much more stylish, but the fabrics are pretty poor (I refuse to buy polyester full stop, but these are still viscose, or cotton so thin it's practically gauze, and everything is unlined) and I can't really see myself still wearing them in a few years' time... Is there any solution?
