Hi Secret
Instant Sexiness/a is tal heavy and gives a stronger confident and sexy vibe. Described as Angelina Jolie in a bottle.
Instant Sexiness/b is tah heavy, a bit softer but still confident and sexy vibe. Described as Marilyn Monroe in a bottle.
For me the difference is my own comfort. I feel too impatient and have been blunt to the point of rudeness when wearing a lot of Instant Sexiness/a, while with Instant Sexiness/b I feel soothed and at ease. As far as reactions go my husband is more responsive to me in B, but he also notices A. If you’re not having a negative reaction to Instant Sexiness/a it is probably the bottle for you. A lot of women here wear heavy Instant Sexiness/a happily. It can also come down to reaction, if your husband is more reactive to tah(B) than tal(A), then you want whichever he is most likely to react positively to.
Reading justonce’s sticky titled Ladies: A mini complilation of your experiences might help you decide too.
