He OMG! HAHA, I can say OMG and that is your name. Good way to shorten it IMO.
Ok, so Creed... Just another niche house. Oliver Creed is the name of the man who is running it now. It has been becoming so popular though that some people don't consider it niche. Although popularity doesn't determine niche VS designer it would seem that it is more designer since it is sold in Neiman Marcus and very easy to find elsewhere.
All bottles are similarly shaped, minus the new Love in White, but they are just a house. There is nothing really special about it unless you love Creed fragrances. They are extremely expensive but worth it to many who wear them.
Some good ones that you might like to try, if you get the chance, are: Bois du Portugal, MI, Acier Aluminum, Neroli Sauvage, Green Irish Tweed, Erolfa, Silver Mountain Water, Himalaya, and so on.
Creed has a very distinct note that links all of the fragrances to this house. Many have tried to figure it out but I'm not sure we know what it is. I don't know it for sure. Creeds are very distiguishable once you smell them. It is easier to single out a Creed than guess what fragrance it is.
So, to sum it up Creed is a very expensive niche fragrance house. There are many great ones that come from this house and probably a good place to delve into if you are thinking about getting more into the fragrance world.
