The closest fragrance clones recreate the main scent profile of an original while remaining convincing through more than just the opening. Similarity can come from shared accords, recognizable notes, a comparable drydown, or the way the fragrance develops from its first spray to its later stages.
No clone should be assumed to smell completely identical to the original. Differences in balance, materials, sweetness, freshness, projection, and longevity can remain even when two fragrances are strongly related. Similarity ratings should therefore be treated as community guidance rather than proof of an exact match.
