Katie:
Great pics!
The central theme, as I see it is to blend in with the other women aroung you. Whatever they do, you should pick up on their movements and try to emulate.
Denae Doyle / FemImage suggests that men walk and stand, taking up as much space as they can.
Women should try to minimize their space needs. She also suggests that keeping arms close to your body gives the appearance of taking up minimum space. Hands should be cupped or otherwise held so as to diminish the appearance of size! I think, for the most part, your pics show a woman. Remember to stand straight and erect, even with your feet and knees in the correct positions.
I think your muscles (arms and legs) are toned and fit. If you present yourself as an athletic person, you should have no problems... Personally, I consider your build as being solid, with the right amount of curves and "meat on your bones" (a guy phrase).
As was mentioned earlier, make sure your make-up is truly hiding what needs to be hidden.
The real clincher will be your walk, on level surfaces and on stairs.
One website worth reviewing would include:
www.wikihow.com/If you google the phrase "walk like a lady" several sites will show up...
You may look great when you are not moving, but that walk could easily be the one thing that may give you away!
You have a great start! Keep up the work! Carry yourself with confidence! Let your radiance tell everyone that you are a lady, as well as a woman!
