Finally! It is done! It took a long time to change a color and to fix it. Of course, if I had nothing else to do in the house, it would be faster, but it is ready to use now!
I sand it until no brown paint and until smooth. I used high quality of white gloss paint. I also painted beige fabric inside the drawers with fabric spray paint. On the sides of jewelry box I had to replace fabric parts with another one and painted it too.
