I think it seems that the 70’s would be more of a challenge for you, which could bring you more satisfactory benefits because you’ll be challenged and have to devise ways to develop your skirts and dresses. I believe you’ll learned more if you pick the option that brings you more challenge. This should push your limits, knew things should come this experience.
Also, androgynous look could have much potential for development because there are many factors that are influencing such look. The process of morphing men/women clothing to fit women/men. That could be something to think about. Remember that those who strive are those who push the boundaries. Good luck and hope my advice helps you!
