One of the Bobbi Brown rules from a decade ago was that if you're going to use shimmer, you should only use it on one feature at a time (and never on the cheeks *cough* shimmerbrick *cough*). I pulled out some Kose Addiction items yesterday, and every single one of them was sparkly. The colours are all quite neutral though, so I don't think I looked too much like a christmas bauble.
Secret Night on its own.
Secret Night with Stardust pressed over the top of it.
Applied - it's hard to capture in a photograph, but you can see hints of the sparkles. It's quite subtle unless you really pack Stardust on.
Dream Pillow applied - which also isn't as sparkly as it appears in the tube, although if you enlarge the photo you can see the sparkles.
What beauty rules do you like to break?
