I will say the original baccarat rouge 540 is ALOT stronger, 1 spray can fill a room easily. While this one is strong, you wont have to air out your bedroom if you spray a few times. lol I compared them both together and tested my husband, he couldn’t tell a difference. They smell exactly the same. I layer this with the body oils, hand cream used as a lotion, and perfume on top. The lasting power is DAYS. There is just something so iconic and different about no. 99 and 540. I wear it daily.
