It's the smell of the perfume if purchased in the U.S. or in the UK?
Friends, I intend to take some perfumes in the U.S., because they are much cheaper here. However, I wanted to know if the smell of a perfume brand Armani say the code, the same in the U.S. and the one sold in the UK or are different. This is because my sister has chosen one back home and go online shopping at the U.S. no idea how it smells. Any help is appreciated
same product, same brand, same smell.
