This is nonsense. Botox and lip filler are a huge and still growing trend. Maybe noticable lip filler isn't a good look (I don't think it is) but these procedures in general are more popular than ever before. Fake tan is also one of THE most popular beauty items available, and is fine if used well. I wear fake tan because my legs are translucent white without it and it makes me feel better. If you mean dark orange fake tan then yeah, not a good look, but tanned skin is not 'out' (how could any skin colour be 'out' without delving in to racist territory) and therefore fake tan isn't either.
Gym wear/tracksuits are everywhere too, including all over fashion blogs! Fancy tracksuits to wear with loafers and a cashmere jumper are everywhere on What/How/Wear etc.
Bright coloured hair has always been a micro-trend rather than mainstream and we should be celebrating these small eccentricities and deviation from exact copycat hairstyles, surely? How can self expression be 'out'? And no, this didn't touch a nerve, my hair is dark blonde.
Burberry and Armani are hugely successful British brands. The idea that you wouldn't buy anything from a brand simply because it's 'out' is mad, whether that brand is a designer one or a market stall.
This whole post seems mad, and the statement that people don't know 'how to dress' suggests there's a correct way, which surely contradicts the entire idea of fashion as self expression and suggests fashion exists purely to prove the ability to conform and consume correctly, like obedient little robots. Surely that's not something to be glad of?
I'm very in to clothes and, although I am obviously swayed by the zeitgeist, I much prefer to focus on what I love and what suits me than following the rollercoaster of what is 'in' and 'out'- and anyway, these lists always depend on who you ask!
