why can the odor of perfume reach you?
The people on the opposite side of the room will be able to smell the perfume due to the process of diffusion, where the vaporized perfume particles move from an area of high concentration (near the bottle) to an area of lower concentration (across the room). This process is driven by the perfume's vapor pressure, which is the pressure exerted by the vaporized particles above the liquid surface.
The phase is called diffusion. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, allowing the perfume particles to spread out and reach your nose even across the room.
When you open a bottle of perfume, the liquid will begin to vaporize at room temperature, and the scent will spread through the air. The smell of perfume reaches other parts of the room because gases have a high rate of diffusion. A few molecules of perfume are enough to let you detect the smell.
The molecules of perfume are in a gaseous state and mixing with the molecules of air in the room. All of them undergo random motion at all times as a result of the internal ("heat") energy that they have absorbed.
We smell because of particles in the air. Air currents , due to people moving about or fans in the room. carry the particles across the room and the nerves in your nose detect them.

It's probably already been sprayed before so it might be on the outside of the bottle where you can smell it. If you're not near it, it's probably a strong perfume or you're in a ventilated room. :)
This is due to the process of diffusion.
well are nose is the one that smells it so you should ask your nose but really the answer is RIBOSOMES
the particle of the perfume diffuses and moves

people down stairs are going to smell good

the smell will spread at the another side of the room
The song "Don't Stop Believin'" by Journey contains the lyrics: "A singer in a smokey room, The smell of wine and cheap perfume..."
