I posted about this on release day and the T-shirts immediately sold out. Not surprising given the huge fan-base that KAWS has and the incredible pricepoint that UNIQLO set for this collection ($14.95!).
Anyway, I managed to pick up a good amount for myself, but if you wanted one and was sad to see them sold out, you'll be happy to know that UNIQLO is planning on reprinting and restocking them soon.
