I have been wearing Uniqlo t-shirts most days for the last few years. The codes change regularly on those. I have a few from a version where the bottom hem is always curling up on itself. The rest of them just hang straight and flat... I also have some Uniqlo underwear that changed code where the old ones fit well and the new ones didn't. I'm still a happy customer, but it does mean that I have to be a little cautious about buying 5 more of something just because my previous experience with it was good.
