One of my most favorite stores in the world Colette is know for their innovation and generally awesomeness when it comes to products and what they sell. Although they are known for their fashion and culture, they also have pretty amazing beauty products.
Recently Benefit and Diet Coke and did a little collaboration exclusively.
The "Soyez Glam" collection features 3 exclusively designed cans of Diet Coke as well as 3 Benefit Perfumes, POREfessional, They're Real Mascara, Cha Cha Tint, Benetint and Posie Tint.
You can buy this amazing set from Colette online but it will set you back 200 Euros, so not cheap. I'm seriously considering buying it because it's that amazing.
