Yves Saint Laurent makes three of the most coveted women's fragrances in the world — Black Opium, Libre, and Mon Paris. Between them they've sold hundreds of millions of bottles, dominated fragrance counters globally, and been the answer to "what perfume is that?" in countless conversations.
They also retail for between $170 and $250 a bottle in Australia.
At The Sweetest Lie, we've built inspired-by versions of all three — same scent profile, same staying power, from $45 AUD. Here's everything you need to know.
Why Are YSL Fragrances So Expensive?
Yves Saint Laurent sits under the L'Oréal luxury umbrella, which means its fragrances carry the full weight of a global luxury brand — designer licensing, high-profile celebrity campaigns, premium retail placement, and elaborate packaging that costs serious money before the fragrance itself is involved.
The actual juice — the fragrance oils, the alcohol, the development — is a fraction of what you pay at the counter. Our inspired-by versions skip the marketing budget and the designer markup entirely, and put that money into the scent itself.
The Best YSL Dupes Available in Australia
1. YSL Black Opium Dupe — Lie 30 ($45 AUD)
Original RRP: ~$200 AUD
Black Opium is one of the most successful fragrance launches of the last decade — a bold, addictive, coffee-and-vanilla gourmand floral that somehow manages to be both dark and radiant at the same time. It launched in 2014 and immediately became a cult favourite, appealing to women who wanted something that felt genuinely edgy without sacrificing femininity.
The opening is coffee and pink pepper — energetic, slightly dark, and impossible to ignore. The heart is a beautiful white floral accord of jasmine and orange blossom. The base is where Black Opium earns its name: deep vanilla, patchouli, and cedarwood that gives it a warmth and tenacity that lasts for hours.
It's the kind of fragrance that gets you compliments every single time you wear it. Lie 30 was built to deliver exactly that experience.
Who it's for: Women who want something bold, warm, and distinctly feminine — a fragrance with genuine presence.
Saving: $155 AUD compared to the original.

2. YSL Libre Dupe — Lie 32 ($45 AUD)
Original RRP: ~$250 AUD
YSL Libre launched in 2019 and became one of the fastest-selling new fragrances in recent memory. It's modern, bold, and unapologetically confident — a fragrance that embodies the YSL woman perfectly: free, powerful, and entirely herself.
The opening is a crisp, almost citrusy lavender — unexpected and striking. The heart is a warm, rich floral built around Moroccan orange blossom. The base is where Libre becomes truly distinctive: a creamy vanilla musk blend that gives it an almost skin-like warmth, making it feel incredibly personal to the wearer.
What makes Libre special is its contrasts — simultaneously fresh and warm, floral and oriental, bold and intimate. It works year-round, day and night, and it genuinely turns heads.
Lie 32 captures that same lavender-floral-vanilla signature — the balance of freshness and depth that makes Libre so wearable and so memorable.
Who it's for: Women who want something modern and sophisticated — bold enough to be a statement but refined enough for everyday wear.
Saving: $205 AUD compared to the original.

3. YSL Mon Paris Dupe — Lie 47 ($45 AUD)
Original RRP: ~$195 AUD
Mon Paris is YSL's love letter to the city itself — a vibrant, passionate, romantic fragrance that captures the reckless energy of falling in love in Paris. It launched in 2016 and became one of the fastest-selling new women's fragrances of the year.
It opens with a burst of strawberry and raspberry — fruity and playful, immediately joyful. The heart is a rich, white floral of peony, jasmine, and datura. The base of patchouli, sandalwood, and ambrette musk creates a warm, slightly earthy sweetness that lingers beautifully.
Lie 47 brings that same passionate fruity-floral signature at a price that makes daily wear completely realistic.
Who it's for: Women who love romantic, fruity florals — something warm, joyful, and irresistibly feminine.
Saving: $150 AUD compared to the original.

Which YSL Dupe Is Right for You?
- Black Opium if you want something dark, addictive, and undeniably sexy. A night-out fragrance that works just as well during the day.
- Libre if you want something modern and sophisticated — the most versatile of the three, equally at home in a boardroom or at dinner.
- Mon Paris if you want something warm, romantic, and joyful — a fragrance that puts you in a good mood every time you reach for it.
Can't decide? Our 4-bottle bundle lets you pick any four fragrances for $135 — so you could get all three YSL dupes plus one more for less than the price of a single bottle of Libre.
How Close Are They to the Originals?
Our fragrances are inspired-by compositions — independently made formulations that capture the same scent profile, mood, and character as the originals. They're not chemically identical (those formulas are proprietary), but they're built to give you the same experience: the same opening, the same dry-down, the same compliments.
How Long Do They Last?
All our fragrances are Eau de Parfum concentration, designed for 6–8 hours on skin and longer on clothes. Apply to pulse points — wrists, neck, inner elbows — on moisturised skin for best results. Don't rub your wrists together after applying; it breaks down the top notes faster.
