I'll try to answer this as a generic question, not specifically for kimono, for which there are perhaps other terms. It can be asked about other professions and skills; how should we describe a woman who is a top chess player, or a conductor of an orchestra? What can be said about an impressive work of art made by a woman? Can we use "chess master", "Maestro", and "masterpiece" in these cases?
The entry "master" in Etymology online begins with "a man having control or authority; a teacher or tutor". This was originally specific to males, with "mistress" as the female equivalent.
Nowadays, as Cambridge dictionary shows, usage of "mistress" with this meaning is outdated. This word predominately means "a woman who is having a sexual relationship with a married man". Usage of this word to describe a woman of authority would be very insensitive.
Although the word "master" is sometimes considered as part of sexist language, and alternatives can be suggested in order to avoid it, it also exists as a gender-neutral word, as shown in Cambridge dictionary: "She was the victim of her circumstances rather than the master of her fate". Women get their master's degree just like men, and a work of art would be described as a "masterpiece" regardless of the artist's gender.
It may not be natural for everyone, but you can call a female chess player "chess master", and a female conductor can be called Maestro. My personal opinion is that trying to find alternative terms for women in these cases would just create other instances of sexist language.
