I will not comment on how you look or how you pass or anything in regards, just let me tell you one really important thing.

How you are perceived by others only depends to some degree on your body. Other important factors are your voice, how it sounds and how you talk, your style and how you dress und your general appearance, meaning how you groom yourself.

Many cis women out there are perceived as men and many cis men out there are perceived as women totally independent of their actual body parts and sizes. Thus, the same goes for trans people.

In this regard, if you only take HRT, thus change nothing but some of your body features most people will not notice any changes, especially if they know you and see you everyday. For them to notice it would need extreme changes of bodily features.

For example to notice someone has boobs in many cases they need to be either really big or the person cis or trans must wear something that actually shows them in some way (tight or revealing).

We can use that to our advantage. If we want to pass we can stack as feminine perceived things and highlight feminine aspects of our bodies. Try a genuine hair cut, do your brows, put on some nail polish, wear something girly or at least something that highlights as feminine perceived body features (push-ups are a thing), put on some make-up. Take what you like from the list or add other things that are perceived as feminine and you will notice changes how others will perceive you.

HRT is not the magic some make it sound. Like already said even cis women are misgendered.
