I have Pleasures Intense and I really notice the lily note. Another very pretty fragrance with a prominent lily note is Lulu Guinness (her first fragrance, just called Lulu Guinness). It's softer than PI, and lacks the strong green note, but your friend may like this.
On Sephora's fragrance finder, they suggest Givenchy's Very Irresistable. I've tried this but I can't remember much about it, except that it is a fresh, bright floral. I think this may work. The other fragrances suggested by Sephora are RL Romance, Burberry Weekend, and AA Gentiana but I can't really say I agree with these. But why not test them out?
I just thought of another one. Lancome Tresor L'Eau de Toilette. This is lighter than the original Tresor and very fresh and pretty. I quite like this, at least from sniffing the magazine fragrance strips. Have yet to really test this on my skin. Lancome's description:
This new fragrance brings together the essence of love with a hint of laughter. An exhilarating accord of Apricot Rose and Lilac represents a light and airy interpretation of Trésor, for the lighter side of love.
L'eau de toilette is an invigorating fragrance form designed to give a subtle but lingering suggestion of scent.
