If it was a blind date, I would probably wear Eva Longoria's "Eva". She created it special using notes that most people are not sensitive to, and insists it is liked by people who are not big fans of strong perfumes. I find I wear that where there might be a lot of people and I was a subtle scent, and don't want to be overpowering.
I might also just wear a body lotion of my favorite perfume, especially ones with citrus notes like DKNY's "Be Delicious" or Bath & Body Work's "Carried Away". A body lotion only gives off just the right amount of scent all over without being too BAM!--SMELL ME!
But... since I am a happy married woman, I change it often for my hubby. My favorite, though, it Stella McCartney's "Stella". Classy/Sexy/Mysterious.... all together!
