What is feminine interior? It definitely depends on the type of a woman :) I'm going to stay rather traditional and show the interiors where light, pastel, light red, purple colors and various textiles are dominating.
I believe that bohemian and romantic personalities would feel quite well in those kind of interiors, while strict and accurate women would get crazy. Each of women knows what's the best and most comfortable for her. Create your home based on your needs and not your friends' or neighbors' homes. Maybe it's a real pleasure to stay there for a day or two but to stay in such an atmosphere for a year can be difficult.
