i would say less trans and more she already fully knew she is a lesbian and just does not care to be put into girls clothing . also my own daughters all love more male looking clothes and forget skirts or dresses hell my daughter sam at her wedding she and her wife both wore traditional clothing for their wedding however as soon as the wedding was over with they both switched into more comfortable clothing no joke they only had on the traditional clothing for less than 20 minutes tops i did not even get a chance to snap a pic even
Lots of girls don't like wearing dresses. You don't have to be transgender to dislike dresses.
Hiromi really seems like she might be transgender.... The manga was almost depression to me because of that. Especially when she was made to wear that dress that she didn't want to wear. It was still cute though.
