Can you people not realise that you shouldn't be asking her why? She has hinted and even stated that she doesn't really want questions asked and you should respect this!
I am sorry I can't give you any direct help though OP as I don't really have any experience on the matter and my fashion sense is awful to begin with any way, although the suggestions I have seen seem extremely helpful and I hope that you achieve the desired look you wish to go for!
In terms of suggestions, although they may seem amateurish, I would suggest baseball caps and long baggy t-shirts and hoodies. This way they should hang off your curves and hide your hips.
Eye brows are also an often defining feature between males and females so perhaps you could get a makeup pencil and draw them to look a bit fuller? Sorry I can't really be anymore help though!
