This eyeshadow duo is not limited edition, and was released as part of the Autumn 2008 Kokoroiro-Himeaka collection. This collection was based around a modern interpretation of the Beni (heart red) shade used in traditional Japanese make-up. The overall feel of the collection was quite gothic and romantic in my opinion, but in a subtle and sophisticated way.
The main shade in the Aijou duo is a neutral greyish blue with subtle shimmer, and it reminds me of the colour of a Persian Blue cat. The highlight shade is an icy cloud blue.
Applied: darker shade in outer half of lid and underneath eye, lighter shade in inner part of lid and blended into crease. Upper lashline lined with Eyeliner Creamy 05 Green Blue.
I like this. I have to be in the right mood for it, as it's very cool toned and quite a dramatic look for me (and it's darker and more smoky in real life - my camera tends to wash photos of make-up applied out a bit.) It's a good way to dip a toe into blue eyeshadow and looks very good with brown eyes.
