Well, I am not a woman, but I'm very familiar with the original L'Interdit, because my sister has worn it for many years. It used to be her signature. Legend has it that this fragrance was created for Audrey Hepburn, and was not available to anyone else, for a number of years. It is extremely feminine, in a strictly interpreted, traditional way. Quite beautiful, but not for everyone. This is an extravagant, French, couturier fragrance that says 'high fashion,' and old time glamour. I do not find L'Interdit to be dated, but some of today's women could find a scent like this, to be effusive. Here are the notes: floral aldehyde: aldehydes, mandarin, peach, bergamot, strawberry . . . jasmine, rose, jonquil, narcissus, lily of the valley, orris, ylang-ylang . . . sandalwood, vetiver, musk, amber, cistus, benzoin, tonka bean.
The 'new,' modernized L'Interdit smells nothing like the original. I don't care for it. Fleur de L'Interdit is nothing special, to me. As for Spring Flower, yes I believe it was created for Audrey as well . . . I am not a big fan of Creed scents. This is a nice fragrance, I smell lots of apple in it, but I don't find that Spring Flower, 'speaks' of Audrey. To my nose, it's just not chic.
