Guerlain will launch Jasminora, the newest addition to the Aqua Allegoria range, this Spring. The Aqua Allegoria line focuses on lighter perfumes for summer wear and is meant to "showcase nature"; the packaging was given an update in 2010.
Jasminora features notes of galbanum, bergamot, cyclamen, jasmine, lily of the valley, musk and amber.
I will update with sizes and concentration when I can find them, but the Guerlain Aqua Allegoria scents are usually in 75 and 125 ml Eau de Toilette. (via parfum-femme.prime-beaute.com)
Update: Guerlain Jasminora is available in 75 and 125 ml Eau de Toilette.
