NARS Blush in Orgasm is a cult favourite for a reason: it's a super subtle peachy pink with chunky golden shimmer that'd suit a variety of skin tones.
The case is your standard NARS soft-touch silky/velvety-finish black rectangle compact - impossible to keep clean, it picks up fingerprints, dust, powders: you name it, it's there and cannot be removed. I hate that about all NARS.
The blush is pressed powder, super powdery but also lightweight and blends like a dream. Perfect for fair/light skin with any undertone.
It's rather long-wearing but not waterproof. A setting spray can help achieve an even longer wear.
This is the only NARS product I've ever tried that I don't actually mind (apart from their foundations). I still think it's super overpriced - not sure why the French think it's okay but a lot of people don't seem to mind it.
