I gave Must a try when I was searching for a fragrance similar to Obsession. Although not the same (which of course it couldn't be), it does has some similar tones. A lot softer and not as long lasting, but a good substitute just the same. I would buy it again, for sure. And from francrancex.com

Great Smell; Not Overpowering; Sensual

Doesn't Hold; Too Weak

I have been giving my wife the Cartier perfume since I first discovered it In 1989. We both love the scent. This variety is almost as good as the original.

...in the early 90's :( very disappointed! The
Fragrance smells way too similar to the Eu de Parfum.
Fragrance blending is a large part of my business
so I can really notice the change.

The smell is entirely different thank the bottles I've purchased in the past. This one is much sweeter. The older scen was more musky with an underlying ambe or patchouli scent.

A LOVELY SCENT THAT COMES ON STRONG, BUT STILL HAS A WONDERFUL SMELL (IMO) AND HAS A NICE LONGEVITY TO IT. I WILL DEFINITELY WEAR THIS PERFUME WITH PRIDE.

...how long it's been since I've even noticed Must de Cartier. It is a revelation to explain how different and special this fluid works in my nose. Earlier, 30 years ago, there was an acquaintance and a friend alike who wore this fragrance frequently: Detlef was a popper, and liked Depeche Mode and...

...it doesn't have much lasting power. I wish they made Must de Cartier in an Eau de Parfum version. The Eau de Toilette seems a little too weak. If you like Must de Cartier, you're going to LOVE Moschino for women (with the gold top and Italian ribbon).

absolutely love it, have used this for about 15 years, fast delivery, no hassles

One of my all time favourite perfumes, not often found on the high street. Subtle and sophisticated.

Not for me, but others seem to love it, I found an overriding chemical sort of smell to it, we all smell things differently, so when I was told about this smelling just like the old Elizabeth Taylor Passion perfume, I bought some immediately, but whatever my daughter smelled in it I certainly didnt.
