About
About this formula
Si EDT by Giorgio Armani is a modern feminine classic that balances radiant freshness with a warm, sensual depth, earning its place as one of the defining floral fragrances of the past decade. Its appeal lies in a carefully constructed tension between luminous citrus-floral brightness and a smooth, resinous base that feels both effortless and polished.
The opening of this reconstruction introduces bergamot as the primary citrus launcher, providing the clean, slightly tart lift that characterises Si's signature first impression. Hydroxycitronellal adds a soft, muguet-like floral transparency that keeps the top tier airy rather than sharp, while geraniol contributes a gentle rosy-green sweetness that bridges the gap between the fresh opening and the floral heart below. Together these three materials create an introduction that feels luminous and immediately wearable.
The heart is where the formula finds its identity. Gardenia brings a creamy, slightly indolic white floral richness, grounded enough to feel sophisticated rather than heady. Rose adds classical feminine structure and a touch of dewy naturalness, while hedione -- the quiet workhorse of countless floral compositions -- opens the whole accord with its jasmine-like transparency and remarkable diffusive quality. Hedione is responsible for much of that radiant, skin-close warmth that makes Si so distinctive on the skin in its dry-down.
The base is built to last and to soften the composition into something genuinely intimate. Cedarwood lends a dry, slightly smoky woody framework, while patchouli adds earthiness without dominance -- used in restraint here to add depth rather than to define the character of the fragrance outright. Galaxolide provides the smooth, clean musk texture that gives Si its well-known skin-like warmth, and ambrox contributes the semi-marine, woody-ambery quality that extends the fragrance beautifully into the dry-down. Vanilla rounds everything out with just enough sweetness to keep the base inviting without tipping into gourmand territory.
This formula is rated beginner difficulty and is well-suited as an entry point into floral-ambery construction. The materials are widely available from standard perfumery suppliers, and the structure is logical and forgiving -- beginners will find the note relationships intuitive to understand and adjust. The 18 percent EDP concentrate level is set to deliver projection and longevity consistent with the original, and the formula includes usage guidelines to help first-time builders scale safely.
This reconstruction suits women who gravitate toward polished, versatile florals appropriate for work environments, social occasions, or everyday wear in cooler to moderate temperatures. It performs particularly well in autumn and winter when its warm base notes have the conditions to develop fully.

Questions
Frequently asked
What skill level does the Si EDT formula need?+
This formula is rated beginner. It uses 62 materials and comes with step-by-step maceration and dilution guidance, so it is suitable even if this is your first build. Every material is listed with its CAS number so you can source the exact item.
Where do I buy the ingredients?+
All of the materials are stocked by the major hobby-perfumery suppliers in the US, EU, UK and Australia. Each material includes its CAS number to make ordering unambiguous, and our free Ingredients Guide lists trusted suppliers by region. Specialty bases are flagged with supplier notes in the formula.
How much fragrance will this make?+
The formula is given per 100 g of concentrate, with grams-per-100g figures for every material, and our on-screen batch calculator scales it to 10 g, 50 g, 1 kg or any size instantly. Diluted to roughly 18% in perfumer's alcohol, a 100 g concentrate batch makes around 500 g of finished eau de parfum.
Is it legal to make a clone of a designer fragrance?+
Yes, for personal use. Fragrance scents themselves are not protected by copyright, and our formulas are original reconstructions — our own interpretations, not the houses' confidential formulae. Trademarks protect names and logos, which is why we describe formulas as "inspired by" a fragrance and never use brand logos. Read more on our blog about clone-formula legality.
What about IFRA compliance?+
Each formula includes IFRA notes. The percentages describe the concentrate; your skin-level exposure depends on the final dilution. If you ever sell or gift a finished product you should check the current IFRA Standards for restricted materials and confirm the maximum for your product category. For personal use, always patch-test and follow supplier safety data.
Can I get a refund on a formula?+
Because formulas are digital products delivered instantly, we do not offer change-of-mind refunds. We will, however, refund or correct any formula that contains a genuine material error within 7 days of purchase. See our refund policy for details.
