I d like u point out what notes used in perfum brings the soapness, because i m interested in a lemony soap vetiver scent, should have this 3 elements .
Although I haven't tried it, Mugler Cologne is supposed to be a soapy vetiver scent. I think Guerlain Vetiver may work, but it's not really citrusy, maybe a little bit up top. Ideally I must recommend this cheapy, Mediterranero by Antonio Banderas. It's got vetiver, it's citrusy, it's soapy. But people I know who have smelled it, either love it or hate it. so be careful.
Ah, a favorite of mine.
D.R. Harris Arlington: readily available British eau de cologne with lemon, soap, and fern.
Crown Buckingham/Anglia Sissinghurst: beautiful English soap (c. 1910s) featuring lemon, orris, pine, and dusky cypress. The new Sissinghurst is good, but the old Buckingham was stupendous.
Blenheim Bouquet/Town & Country: two similar offerings of juniper, lemon, and pepper. Beware of Penhaligon's recent reformulations.
Rigaud Eau de Kananga: The perfect French barbershop soap of the 1920s; citric soap with light florals, musk, and carnation.
d'Orsay Le Dandy (vintage): yet another soapy, yet much darker contender of Kananga.
Apart from seconding Mugler Cologne, I'd also recommend ADP Colonia and Colonia Assoluta (true, neither of the two have a vetiver note, at least no significant or detectable one, but the soap and the lemon in both of them is sufficiently strong, to come off as almost pleasantly grassy and/or resinous, thus quite close to vetiver).
