First of all, let's analyze the source of body fragrance. Girls are also human beings, and they also secrete sweat and various liquids. If they don't pay attention to hygiene for a while, they may stink. So it makes sense to say that there is no so-called "body fragrance". Don't imagine a girl as a white and flawless fairy figure who exudes fragrance from the inside out and is surrounded by a pink halo.
Girls are cleaner than most boys. Whether it's soap or shower gel, daily skin care products, washing powder and shampoo for washing clothes, they all have flavor. Some girls use perfume just to make themselves exude charming fragrance.
This is likely to be questioned: my girlfriend has always had the fragrance of peaches, and it has always been a taste. How do you explain this?
If girls think peach-flavored shower gel is easy to use, they should always use it, or they just like peach-flavored things, from head to toe.
So to sum up, the so-called body fragrance of girls is the result of "pickling and tasting" cosmetics, skin care products and toiletries.
Not all girls are fragrant. When I was in college, I joined the health department of the student union and was lucky enough to be in the girls' dormitory. Some dormitories are delicious as soon as they enter, which really makes people feel relaxed and happy, and there is an inexplicable warmth in their hearts. There are also some dormitories with smelly feet, yes, they really stink, and there are shoes with dirty socks on the ground, which is as messy as boys' dormitories.
In fact, almost every girl who goes out is glamorous. Perhaps this so-called body fragrance is also a carefully managed "artificial fragrance".
