Shama-il Tirmidhi Chapter 32, Hadith Number 4 (210).

Abu Hurayrah radiyallahu anhu narrates: Rasoolullah sallallahu alaihe wasallam said, The itr of a male is the fragrance of which spreads and has less colour in it (i.e. rose, kewrah etc.), and the itr of a female is that, which has more colour and less fragrance (hina, mendhi, za’faraan etc.).

Males should use a fragrance that is masculine, as colour does not suit them. Women should use a feminine fragrance, which does not give off a strong fragrance, it must be such that its fragrance does not reach strangers.
