Oh yes. Bvlgari Soir is definately similar to Bulgari PH. However if you are having longevity issues, I would suggest you should try Bvlgari PH Extreme. All three of these have that distinct Bvlgari "smoothness" and are based around that note so they are all similar. Bvlgari PH Extreme is just the longer lasting version of Bvlgari PH.
