GB--Knowing has an extremely long and drawn-out development--in an hour or more, the floral comes out a bit more. It has amazing longevity too--12 hours or more.
Shalimar EDT, I find it smells horrendous. Reminds me of baby wipes--bleck. I love the EDP and parfum.
And Jicky...love it. It needs to go on skin! The stronger concentrations do have alot more lavender, I find. They may be more satisfying than the lemon-drop quality you got in the EDT.
