Sleek's Rose Gold is a beautiful rosy blush with golden shimmer running throughout (full review here). The shimmer is noticeable but very subtle - it merely gives a flush of colour with a soft glow. I purchased it with the Face Form Palette in Fair from Sleek, but it is available to buy individually also.
The Chanel Rouge Coco Shine Lipstick in Shade 62 Monte Carlo (full review here) is similar in colour, a reddish-rosy pink with a slight warm shimmer. This applies with a hint of sheer colour, but can also be built up to a more opaque look, always with a glossy, hydrating finish.
I have loved wearing these two products together - they compliment each other so well. Both have that similar pink tone that isn't too in-your-face, and a subtle shimmer that is only used to enhance features and create a healthy glow. I can see myself wearing this combination all through Spring and Summer, they both give a beautiful, noticeable but fairly natural look that really lifts the face.
Do you have any products that you love to pair together? I'm going to have to get experimenting and find some more in my collection!
