I am trying to find a proper word for describing a visual concept.
At the moment the closest description is "understated sexuality", but maybe there is another word to describe a woman that is beautiful, attractive, sexy, confident and at the same time modest?
"Majestic or glorious" (Eilia 2015) "are too lavish, I need something different." (maxlaks 2015)

You can't throw a bunch of adjectives together and expect English to cough up some magic word. It might happen, but then again, it might not.
If you want to focus on her beauty, use
If you want to focus on her appearance, you could try
For confidence, try
Modesty, in some senses, goes against confidence, but you can use
For understated sexuality in particular, I'm partial to
elegant
or, in extreme cases
sensuous

PS - In my humble opinion as a reader, I like writers to describe girls with as many specific adjectives as possible, rather than be too laconic about it. Even your description in the post would mean more to a girl than any single word could.
