If you are curious about the smell inside this unique bottle, but do not have an easy access to it, I would recommend trying Jeanne Arthes "Sultane".
This one, in accordance with the more 'sensual' shape compared to the fancy bottle of Sultane, is like its mature (or, more advanced) version - more musky and with an oily undertone. While both fragrances have similar notes, the only difference for me is the weight or density. In addition, the peach in Sultane has a stronger tea-like nuance, and the whole composition remains lighter than the Tuscan Soul, which seems to be melancholically inclined - a sultry, peachy floriental, suitable for cooler seasons.
Someone who generally prefers the 'warm, sensual, cosy' type of fragrance (and peach flavouring in particular) might appreciate this more. For my part, I couldn't wear it in either variation, but I'm still intrigued by the peculiar headpiece - resembling a sauna turban, glass noodles or water poured out from an urn.
Edited to add: As Dr.Ricaud latest pyramid reveals, my nose was not mistaken about the proximity of Âme Toscane to Arthes' Sultane - the top and base notes are identical, the heart consists of a similar set of peach and a white florals (jasmine/freesia), leaving the 'Tuscan iris' as the distinguishing note. A heads-up for the fans of the uniquely shaped bottle: it has now been given up in favour of the unifying trend.
