Currently I use small breast forms combined with loose shirts so they are not obvious. This was easier before I lost a lot of weight over the last four years, so I no longer have the big belly to make the forms look proportional. When home alone, I wear bigger forms all the time, which really helps.
I have also started shaving my arms since the body hair is one of my dysphoria triggers. No one has said anything about my arms so far, so I plan to keep up with weekly shaves of them using a rotary razor. They do not need to be smooth, just not obviously covered by hair.
