as said by someone else. go to Royal Plaza and go to paris gallery. Girls in there are good. Just tell them that you want a strong, long lasting perfume..and they will spray away and give you coffee beans in between to neutralize your nose!

strong ones include some made by the following brands-:

Guerlin
Kenzo
Dior
Bvlgari
Micalef (winter version is super strong)

If you like the oriental with a hint of euro, then Al Jazzerah perfumes has some very long lasting perfumes.... they are very concentrated...... their are ones in gold canister type bottles....... ground floor at royal plaza.
