You might remember that Shu collaborated with photographer Mika Ninagawa for their 2008 holiday collection. They've paired up again for a smaller collection this spring called Sakura. Unfortunately it doesn't seem like the U.S. is getting the stuff with the pretty designs – just the lipsticks. No fair!
I can't say much else about the collection except that it would seem plausible that the images on the products are cherry blossoms. I don't know fore sure since they're only available at the Japanese Shu website and I can't read Japanese.

Le sigh. I may try to track these down on E-bay!
