Quick Verdict

YSL Y EDP is the overall winner for its incredible versatility, longevity, and crowd-pleasing freshness. It works for the office, a night out, or a casual weekend. By the Fireplace, while stunningly unique and cozy, is more of a seasonal specialty scent. If you can only buy one for year-round wear, choose Y EDP. But if you love a smoky, sweet gourmand for cold weather, By the Fireplace is unbeatable.

Scent Profile Compared

YSL Y EDP: The opening is a burst of crisp apple, ginger, and bergamot, sharp, energetic, and slightly green. The heart brings sage and lavender (though not dominant), and the base is a woody-amber mix of cedar, ambergris (synthetic), and a musky tonka-note. It has a plasma-fresh, shower-gel vibe that’s undeniably modern. The drydown is smoother, less sweet than the opening, with the woody-amber base lingering.

Maison Margiela Replica By the Fireplace: This is a literal interpretation, a photorealistic scent of sitting by a crackling wood fire. The opening is explosive: clove oil (almost clove cigarette-like) and a boozy rum sweetness. Then the heart emerges: chestnut, guaiac wood, and heavy, smoky cade oil. The base is vanilla, Peru balsam, and cashmeran, creating a sweet, sticky, roasted marshmallow and toasted wood aura. It’s less complex than Y but far more evocative.

Key Difference: Y is fresh, clean, and synthetic-leaning; By the Fireplace is dirty, comforting, and natural-smoking.

Longevity and Sillage

YSL Y EDP: This is a beast. On my skin, it lasts 10-12 hours easily, with moderate-heavy projection for the first 3 hours. It leaves a noticeable trail without being cloying. Even after hours, it remains a personal scent bubble. Great for all-day wear.

Maison Margiela Replica By the Fireplace: More moderate. I get about 6-8 hours longevity, with moderate projection that quickly becomes intimate after 2 hours. It’s a skin scent sooner, but the smoky sweetness lingers close. It won’t fill a room but invites close encounters.

Verdict: Y wins on longevity and sillage. By the Fireplace is more subtle.

Best Occasions and Seasons

YSL Y EDP: Versatile for all seasons, but shines in spring, summer, and warm fall/fall days. Perfect for the office, dates, casual outings, and clubbing. It’s non-offensive and confident. Avoid in extreme heat (can be a bit sharp) or formal black-tie events (too sporty).

Maison Margiela Replica By the Fireplace: Strictly fall and winter. It’s best for cozy evenings, intimate dinners, cold-weather dates, or a night by the fireplace. It feels out of place in summer or at the gym. It’s also great as a room scent. Not for office wear (might be too divisive or smoky).

When to wear each? Y for 80% of your life; By the Fireplace for the 20% cold, cozy moments.

Price and Value

Both are designer-priced, but check current price on Amazon for the best deals. YSL Y EDP is more expensive per bottle, but you get a useable, long-lasting scent that needs fewer sprays. By the Fireplace is slightly cheaper, but due to its moderate longevity, you may use more sprays. Consider that Y covers more occasions; By the Fireplace is a specialized purchase. If you’re a collector, get both. If for one signature scent, Y wins on value.

Which Should You Buy?

Buy YSL Y EDP if: You want a versatile, masculine fragrance for daily wear that lasts all day. It’s the safer, more practical choice for any man’s collection. Ideal for businessmen, young professionals, or anyone wanting a signature scent.

Buy Maison Margiela Replica By the Fireplace if: You love unique, atmospheric scents, or you’re specifically looking for a smoky, sweet winter fragrance. It’s perfect for date nights, holiday parties, or if you want to stand out with a conversation starter. Not a summer or office scent.

Final advice: Start with Y for all-around reliability. Add By the Fireplace as a cold-weather treat when your budget allows.
