Sorting Out Prada Infusion d'Iris

I see on another website that Prada launched Infusion d' Iris in 2007. Was this 2007 launch an EdT? If so, how does one explain Prada's launch of Infusion d' Iris EdT in 2010? Is this a totally different fragrance from the 2007 launch? The colour of the 2010 launch looks greener, and according to the other website, it has slightly different notes.

The upshot is I am confused and would appreciate it if anyone could explain this to me.

Hey Oriane,
It seems they differ in concentration and notes.
- Infusion d'Iris (2007) Eau de Parfum
- Infusion d'Iris Eau de Toilette (2010)
- Infusion d'Iris (2015) Eau de Parfum
The latter looks like a reformulation of the original EdP. Not much of a help, I'm afraid.

Hi. Yes, it seems they must have reformulated the original EdP, but I cannot understand why as it was so popular. I have had the EdT and EdP on my test list for a long time. I have a sample of the EDP Absolue arriving today. If I really like it, I may order samples of the regular EdT and EdP. I think the reason I have never ordered samples until now is that I have been worried Infusion d' Iris was going to be too clean and simplistic.
