I love clothing and fashion and one icon that everyone seems to know, but not as many can afford, is Yves Saint Laurent.
I have that brand! My mom has passed down some clothing from that brand, because it was founded way back in 1961. She still gives me some perfume from them, because they have a notable presence in the luxury beauty fragrance market, too.
Oh neat!  I bought a blouse from eBay before and loved it.  I wore it to death! How many categories of items do they make?
They're a prominent fashion house known for modern and iconic pieces, like tuxedo jackets for women. But they have a broad range of women's AND men's ready-to-wear products. So we're talking leather goods, shoes, and jewelry, as well as perfume, like I mentioned.
I have never smelled the perfume before.  Do they have multiple scents or just one signature?
You probably know their perfume maybe under a different name, because their perfume line is owned by L'Oreal, which holds exclusives licenses for the name.
Oh, wow. I didn't know they owned L'Oreal too. That makes sense to have a high end brand and a more mainstream brand to be for more people. 
Exactly! More specifically regarding the  Yves Saint Laurent brand, however, you might find it neat to know that during the 1960s and '70s, they popularized a lot of fashion trends. These includes the beatnik look, things like safari jackets for men/women, tight pants (sound familiar?), and tall thigh-high boots. One of their most famous is the classic tuxedo suit for women in 1966, which I mentioned. It's called Le Smoking suit, haha.
I had no idea they made tuxedo suits for women that long.  They were really groundbreaking in everything and its all coming back around again today. 
The actually designer, Yves Henri Donat Mathieu-Saint-Laurent, was a visionary. He's regarded as one of the most foremost fashion designers of the 20th century. Someone notable wrote of him in 1985 and said, "The most consistently celebrated and influential designer of the past twenty-five years..."
