First off, only amp up your femininity if it’s what YOU want to do. I already know you are an amazing girl, fem or not, so don’t put to much thought into it. I have tried playing more fem and more masculine for guys, it never works out. But if you really want some fun tips for giving a little more femme fierceness, here you go.
As far as carrying yourself more femininely, I’m not too sure because I kinda just always remember being feminine. My icons include Marilyn, Madonna, and Naomi. These women evoke soft and sensuous femininity, but still hold alot of power. Never lose your power; that’s so NOT femme.
