@p4 those AW11 pants you posted are one of my go to YY pants period. That bunching at the waist is such a great feeling when done especially with the full volume of the pants billowing out around my legs below. Really great look. Would have picked up the grey ones in that runway shot there, but they only had a size 2 left when I asked at the flagship.
Something that's really cool about Yohji's pants is really the way you feel when you move in them. Like you said earlier, you feel dressed up and relaxed at the same time. Makes it really easy to stop caring about what one is actually wearing as long as it consists of said pants and a top that is equally as loose. Colours, proportions and other considerations be damned .
