I only have 2. I don't really hate these, i just don't understand them.

First one is fake pockets on jeans or jackets - What is the point of having non-practical pair of pockets on the back of your jeans or inside your jackets? Not only that but if you sit down on a bench and your fake back pocket gets stuck in between bench, you may rip it.

Second one is white shoes in formal setting... I see this in UK with British people who clearly have no idea about fashion, which is weird since classic cultures began in the UK such as punks and goths. Why would you wear white shoes, with mud stain on them and a black uniform and attend like this to a formal party, office work, funeral etc? At this point stick a black tape around the white stripe on your shoes....

Well, I will add another one - its not so much for clothes but fake nose rings, you don't look edgy, alternative etc. You look sad in them - which is probably true since sane person wouldn't wear a fake nose ring, it costs only 10$ / 15 British pounds to get a REAL nose ring attached - or maybe you shouldn't try to look different if you have no money
