I dress 'in between' all the time. I mix modes & clothing almost every day. It *is* possible to do, but I think it is a more complicated approach than just doing one or the other (Not to diminish the efforts involved in "transformative dressing"). You have to figure out where the edges are, where things are close to crossing over between 'butch' and 'femme' without crossing over.
I might wear a skirt to the market, or dress in slacks and a pretty girl top. My hair might be in a severe pull-pack into a pony tail or be loose & floofy. I might be wearing eye makeup along side my tattoos and beard. I might be in 'guy mode' clothing with shiny fingernails and earrings.
Lots of options available, you just have to find ones that fit you.
