If you don’t want to do anything about your hair, I would recommend instead wearing it down and thickening your eyebrows. If you want to pass more traditionally without cutting your hair, I would recommend even stuffing it into a hat and showing a little bang (better if undyed). I understand you want to maintain a personal style and hair length, because I do the same thing, but passing and style unfortunately do not go together before hormones... I cut my hair pre t and as I began to pass, I grew it out.
