In a word, yes.
Part of my internal body sense often involves a feeling of having a woman's physique in spite of being apparently 'male bodied'. This is an immediately physical experience - female skin, female shape, female size, and so on. It does not include anything 'external' such as clothing or accessories, minus a bra.
So part of my internal body sense includes the sensation of wearing a bra. When I actually put one one, then, the sense of congruence is wonderful on several levels.
