My jeans sizes are a size 34 leg and a 32 waist. Like I said before, I'm tall and skinny. Although I can wear most of my jeans straight, I tend to fold the hem up once. Maybe it's in fashion, maybe it's more comfortable, I'm not sure, but in winter, I fold them over twice. The logic is simple, in winter we wear boots, and the higher the hem, the less the possibility of it becoming wet.
Most of the time I'll wear them stuffed inside socks, especially when I have my Red Wings on. With these Timberland boots however, I wear the hem folded double.
