Oi! I'm only 24 and I like next jeans.
To be honest though they aren't quite the same as Primark or BHS jeans, starting with the price, which is around £40 a pair. I used to wear Levis but just didn't like them after a couple of years, they are too plain IMO (I always think of Levis as old people jeans)
True but there are trendy jeans in next and old man kfc jeans.
