I am 35, 5'5" and a size 20 and need to sort out my look. My hair is long and wavy and I struggle to do anything more complicated than a ponytail. What would people suggest that I do clothes and hair wise to look like an accountant? I have just started working in a small practice and and am the only woman hence nobody there to get inspiration from. I also feel the cold something awful and cannot wear heels due to balance issues related to my disability.
