18 – Inspired by Si | Naked Formula
Introducing 18, a smooth, elegant fragrance from Naked Formula, inspired by the timeless sophistication of Si. Soft yet powerful, this scent blends fruity brightness with warm sweetness and gentle depth, creating a modern, feminine fragrance that feels refined, confident and effortlessly wearable.
This isn’t a direct copy — it’s a refined reinterpretation. 18 captures the signature balance of freshness and warmth found in Si, reworked into a long-lasting fragrance that delivers luxury character with everyday versatility.
Fragrance Profile
18 opens with a soft burst of juicy fruitiness. Subtle blackcurrant-like notes bring a slightly sweet, lightly tart freshness that feels smooth and inviting rather than sharp.
As the fragrance develops, a delicate floral heart begins to bloom. Elegant florals add a refined, feminine touch, blending seamlessly with the fruitiness to create a balanced, sophisticated core.
The base is warm, smooth and gently sweet. Soft vanilla and light woody undertones create a comforting, slightly creamy finish that lingers beautifully on the skin, leaving a subtle yet memorable scent trail.
Who It’s For
18 is perfect for those who appreciate elegant, modern fragrances with a soft sweetness. It suits:
- Lovers of fruity-floral scents with warmth
- Those who enjoy smooth, feminine fragrances
- Everyday wearers looking for a refined signature scent
- Anyone wanting a versatile fragrance that works day or night
It leans feminine, but its balanced sweetness and warmth make it appealing to anyone who enjoys soft, sophisticated scents.
