ah, tsubi's in t.o.....I highly doubt anywhere in t.o. would carry tsubis, let alone know what they are!!! I was in t.o. a few weeks ago and I didn't see them anywhere, heck the over the rainbow staff didn't even recognize my tsubis.
Tsubi's are pretty comfy and the quality if pretty good! I have a couple pairs myself, but I'm a Canadian that has been living in Sydney the past few years.
I know that there's supposed to be a tsubi's store in nyc, will check it out in a couple weeks when I'm there to see how it compares to stock in Sydney. I also remember seeing them at bloomingdales in soho in January of all places! But they costed $350 US (the same pair was $250 AUD, which is under $200 US).
Just to let you know, tsubis are becoming VERY common in Sydney, just take a walk down Oxford St. in Paddington or anywhere in Bondi and every other person has them on! They were very chic and cool a few years ago, but have become almost regular jeans in Australia.
Just my two cents
