This is a classic fragrance from Estee Lauder . I have worn it on and off for many years , and it is still at the top of my list of sophisticated perfumes. This perfume is heady and strong. It is not for everyone. It has been around since the late 80's and is still very popular today.

I have worn this fragrance for a long time and I continue to have friends compliment me on how good it smells. Some friends even walk up just to smell my perfume. I can't say enough about Knowing. It is my signature fragrance!

Very disappointed with this cologne. Five minutes after spraying, absolutely no smell and now I'm not able to get a refund. Very upset and will not be ordering from amazon again.

I LOVE THE SMELL OF KNOWING AND NO MATTER WHERE I GO I AM ASKED WHAT FRAGRANCE I AM WEARING. EVEN MY DOCTOR HAD ME WRITE THE NAME DOWN SO HE COULD BUY IT FOR HIS WIFE.

I neverrr usually buy perfume online without smelling it, but after reading a bunch of reviews about it I had to get it. And let me tell you I am in loooove. It smells so classy. Literally the first day I wore it 2 people stopped me to ask what perfume I was wearing.

Perfume is a very personal thing. I love this aroma. To me it is sophisticated without being overly sweet. I get compliments constantly when I wear it, although I am aware that perfume is enhanced or made worse by an individuals own personal body chemistry. For me, this is a perfect match.

I purchased this bottle of Estée Lauder Knowing as a Christmas gift for my wife. This is a product that I know she will enjoy. The fragrance is a delight to the senses and strangers, both male and female, often ask for the name of this distinctive fragrance.

I've worn Knowing for well over 20 years. At first I wore it to work, church & special occasions. I cannot recall a single day I wore it that I didn't receive a compliment. Now I wear it everywhere.

If I "Knowing" then what I "Knowing" now, I would have been using "Knowing" much earlier; however, I usually do not spend as much on my fragrances, but it does last a long time. Very pleased with it.

"I've always perfumes. Perfumes of yesteryear are oakmoss-heavy. Therefore, I've always oakmoss." Suffice it to say that when an oakmoss comes along and is friendly towards me I am delighted. It is a rare occurrence but one which I welcome. I hold dear the scents that have survived... Read more
