Nice descriptions, Tovah! I only tried the first J.Lo fragrance, and it was an OK scent, not bottle-worthy for me. Now I have to go try them all on, after reading your reviews. Like they say: "Nose knows!" :-)
Seriously, here is what I came up with. Jennifer Lopez participated in creation of all of them while working with:
Glow -- Louise Turner,
Miami Glow -- Caroline Sabas,
Love at First Glow -- Steve DeMercado,
Live -- Dominique Ropion.
