male to female hormone therapy, how long till can't hide?

It's such a YMMV thing that it's hard to give a ball park figure, but the biggest variable is going to be your chest. Small boobs are easy to hide with tight sports bras and baggy clothes, but bigger ones can be difficult to hide without a binder and binding can have negative side effects on breast growth that most trans women would likely want to avoid.

That being said, personally I've been on hrt for almost 3 years, post op ffs, and still 'present male' without any issues(no male fails or people seeming confused about my gender). I did come out to a couple family members before I had ffs, at around 18 months of hrt, and they had no clue I'd been taking hrt.
