Uniqlo This is the Nishikori model, top and bottom set. Both top and bottom are size S. My wife bought these a few years ago and usually wore them as loungewear. They show some wear and tear (pilling), and the pants are slightly sun-faded, so perhaps they would be suitable for a collection. Please note that the pants do not have a drawstring at the waist. I would appreciate it if you could understand this before purchasing.
