1. Ponchos - were in fashion in the UK a couple of years ago and they still pop up occasionally. Not Clint Eastwood style ones, but short, unflattering, sythentic yarn in barbie pink or pastel blue. Yuk. Especially if you have big boobies. Double yuk.
2. Ugg(hhh!) boots. Were ironic for about 5 seconds, but it still didn't stop them being gross. I have more respect for people who wear 80s moon boots, yeti boots or Mongolian boots.
3. Too tight ladies blouses. Maybe this is a UK thing, but if you are anywhere over a B cup, most ladies blouse these days are so slim fitting you get unsightly pulling and even fullbracupexposure! OH NO! Go up a size and and the only place they fit is the boobs. Thankfully this is changing with the astonishing rediscovery of the miracle that is draping. My beautiful pin tucked silk blouse from Principles only cost $100.
I like cropped trousers, but nothing longer than a couple of inches below the knee. I think they look great with platform sandals or 40s style heels. No cropped trousers on men, ever. See the hobbit comment somewhere above. I'm personally starting a crusade to bring back plus fours and pedal pushers.
I think I may be the only one who thinks that low cut skinnies look better on girls with a figure. I think the skinny girls wearing them tend to look like denim tubes. The problem with excess porkage hanging over the top is just because they're poorly cut or someone is wearing a size too small. I have an old 70s dressmaking book that states the greater the difference between waist/hip size, the lower you go! I put it down to modern attitudes to women with figures. Regardless, I only like skinny jeans with boots, not shoes.
Conversely, wide leg pants look better on skinnies, unless they are well cut (which eliminates a lot of off the peg stuff). Why do they try to get larger ladies to wear them? Personally I think they look awful and I am a former larger lady. It's a conspiracy I tell ye! I tried to get some yesterday. I'm fairly slim but I do have a butt! All of the ones I tried yesterday were tight in the butt but so flared on the leg I couldn't go up a size without looking like I was being assaulted by a giant pair of clown pants (I am quite short, which probably doesn't help).
Really, we need more straight legged, flat fronted trousers in shops. They pretty much suit everybody.
Don't listen to me. I pretty much do my own thing, and think that ADAM ANT is the height of sartorial elegance.
