So finally even I have done a layering, and it worked! I layerd Omnia with Samsara, and that brougt out a mixture I really liked. Omnia is a bit close to the skin, but has a beautiful depht. Puting Samsara above, the result was Samsara with a darker deeper background.
DH liked it, too, but after a question from me, not spontanious.
I will wear this again, this brought someting to Samsara that I liked very much.
