According to reportage, the stunning actress - for some years now an ambassadress for Givenchy and the face of the new fragrance Very Irresistible L'Intense - says "she doesn't like to change her fragrance as she wants people to recognise her smell but hates it when the scent is too much".
She's quoted as saying: "I like having one perfume that I wear all the time, so it becomes part of you. When someone remembers your scent, it's incredible. I don't like it when you first spray on a fragrance. It's nice when you've put it on in the morning, then in the evening, you can subtly smell it." [source]
Of course she's quick to point out that the newest Givenchy is her favourite. As if she wouldn't. Doesn't really matter: Liv is lovely whatever she wears.
