@beardalaxy well important to member that there's a misconception that perfume is ladies and cologne is mens. it actually has to do with the concentration and how long the scent will last. so it goes, Parfum > Eau De Parfum > Eau De Toilette > Eau De Cologne > Eau Fraiche.
Generally speaking Parfum is 8-6 hours, EDP is 5-7, EDT is 4-6, EDC is 2-4, and EF is generally 1-2.
Edit I'm wrong on the times apparently but I have found that some EDT's like CK's Truth last well beyond 3-4 hours.
