My favorites change from time to time but I have a few staples, both old and new, that I will never be without, such as:
BeneFit Maybe Baby
YSL Baby Doll
DKNY Be Delicious
Aquolina Pink Sugar
Nina Ricci Les Belles De Ricci (one of my all time favorites but is discontinued)
CK One
Comptoir Sud Pacifique Vanille Abricot and Banane
and last but not least
LUSH Snowcake Fragrance (only have one bottle of this and am praying for the day they remake it!)
