My favourite product from Chanel has to be their Illusion D'Ombre Eyeshadows- I currently own Emerville, Mirifique, and now the latest 'Mirage': a shimmery golden copper shade. Mirage shines beautifully in the reflection of the light, and is versatile enough to create both a day or night look.
It comes with a mini Chanel eyeshadow brush but to be honest, because the texture is so creamy I prefer to actually apply it using my finger. The colour is also very build-able so whether you prefer a subtle or a bold look, the eyeshadow can, and will deliver either. Plus, the formula being incredibly soft allows you to blend it well.
