Undecided Question

Hair style for square shape?

I have a square/rectangular face shape. I have VERY fine, dark hair. Its short, but long enough to be pulled back in a bun. I work in skin care, so im constantly in front of a steamer, and it causes my hair to stick to my skin and become wavy. I usually wear side sweeping bangs, but when i work, i center my bangs almost in the middle so my hair wont stick to my forehead. Im trying to find a way to style to where i still look professiona. Im sick of the usual "ponytail".

With my face shape, it is hard to compliment it. I am in need of some professional advice.. can someone help?
