im still fairly clueless about pants. so i have tons of questions about pants. 1. what does boot cut mean? 2. the difference between low rise and high rise, is it merely where it sits on the waist/hips? or are there curves in the top of the pant? 3. are there such things as low rise dress pants? 4. five pocket pants, the 5th pocket is usually where exactly? 5. why aren't dress pants ever buttoned?
