Ok...a few months ago I bought a bottle of YSL M7. I was at a small Fragrance shop in Palm Springs. They didn't have a tester so the clerk opened a box and it was what I believed to be vintage (amber glass, dark sides). I got my box (a sealed one) home and opened it and it was the reformulation bottle. I went back and explained to the clerk who didn't seem to know much about M7 or care. He exchanged it for the one he opened. But he put it in my original box. I have no date codes specific to my bottle as such. The bottle I have has the code cut out at the bottom. I've heard thIs happens in gray market. (?). I have no way of verifying if this is a vintage formulation. The bottle would indicate that it is. Scentfreak had sent me a small sample of his vintage M7 and to my nose they are the same. But after smelling and smelling and smelling I can almost talk myself into them being the same and also being different. Thing is...I don't really care and don't particularly like M7. I'll be putting the bottle up for sale soon. Is it possible to have a reformulation in what is accepted to be the vintage bottle? Don't want to represent it as such if it isn't.
