This one's a proper trip down memory lane for many. It's a cheerful, fruit-forward scent, mostly green apple and vanilla, but be warned: some reckon it's a nostalgic gem, others call it a candle or kids' shampoo. Longevity is a real coin toss, so prepare to re-spritz.

Dupe Noire captures Black Opium's coffee-and-vanilla gourmand backbone - bitter almond, black coffee and liquorice over a patchouli-vanilla base - reasonably well, though the coffee note sits lighter and less roasted than the original's jolt, and the whole thing softens into a simple sweet musk rather than YSL's darker, more addictive dry-down.
