Perfume can be very harsh on many materials not only leather, depending on what perfume too, those with high alcohol content can cause major damage. High Alcohol Content usually are cheap or bootleg perfume. Michael Kor leather are ok quality, even you splash it on other Premium Label leather more or less same damages will occur. Nail polish remover is another killer, a drop can cause irrecoverable damages to any leather, they can remove aklot of stuffs other than nail polish, some are even harsh on skin, they are great all purpose cleaner & remover for some hard to clean jobs.
It is not Leather cheap or whatever. A leaking, cracked bottle of perfume left on television top unknowningly, left a big discolored mark there, my personal experience many years back, at that time it's my first flat screen, it is new too at that time.
