Pass on all of that stuff. I also got a nice chuckle out of the "formal sweatpants" bit. @malcolm actually it is supposed to be formal if you read the descriptions of the united arrows website which was posted above. Expensive as hell for some very basic sweats, almost on the level of the boucle sweats.
That is not the USD price of the collection. Japan retails differently from the United States due to import and currency and is more expensive.
