So true about the frills and features on cheap nasty clothes - I wish they would make them simpler but out of better fabric and longer.
I do have some nice quality things. An amazing coat from Hobbs that's beautifully designed, lovely fabric and has lasted years and still looks new. It was about 180 in a sale, 250 originally so expensive, but not crazy designer expensive. Also, I know it's not for everyone but my Superdry stuff is surprisingly well made. You can avoid the logos and get some lovely dresses, cardies and tops - I like them because they make things long enough for me.
I don't have loads to spend on clothes but I have nice things from Toast, Noa noa, Orla Kiely etc that I've got on ebay. I'm a sewer so I can adjust things, change a neckline etc.
I think a number of stores have gone down the route of loads of choice, very quick fashion-responsive manufacturing, and horrible cheap fabrics. Understandable at Primark I suppose, but it's started happening at Whistles, Boden, Gap, and definitely M&S and so on so you feel surrounded by crap even when you're prepared to spend more. But I do still think if you know how to spot quality, it's out there.
I personally hate seeing a fabulous print dress that I love, then find out it's 100% polyester. Immediate turn-off and I won't buy it.
And yes to the high necks, they look good on approx 1% of people. Why do they do it?
