Not a Perfume is built around Cetalox: clean, softly woody and ambery, with a warmth that blends into skin. It stays fairly linear, so the small differences in sweetness, texture and strength matter more than a dramatic change of notes.
DUA #NoPerfume is the closest pick here, though it can feel fuller and less sweet than the original. Dossier Musky Musk adds a more noticeable woody-musk cushion around the same clean idea.
