Dior J'adore, at Sephora, back when it used to be an expensive but still affordable perfume. Now it's 100€ for a bottle, ridiculous !
I think my most expensive bottle right now is Vivara from Emilio Pucci, around 80€ but it was a set i bought for Christmas (one way to justify the price of your perfume is to wait for the Christmas sets !! It doesn't cost so much if it comes in a travel makeup bag with a small shower gel

).
I got a sample of Chanel n°5. It smells good in the bottle (although nothing really original, Chanel fans forgive me) but on me it turns rancid (if that's even possible). Not for me.
