I bought a bunch of shoes without trying them on as the cover story was always something along the lines of "buying them for my mother/girlfriend" and if they didn't fit I didn't return them because that would have been suspicious.
Later when I was brave enough to go out as a girl and go shopping but not brave enough to come out to my parents I had these various methods to dress up before going shopping at night.
When I dressed up at home, I waited until my parents were asleep and sneaked out of our apartment.
I used the elevator to go to the top floor, silently walked up to the roof and used the corridor there to reach the neighboring staircase, then gone down with the other elevator and exited the building from the neighboring street number. When I went home I did the same in reverse, go to the neighboring entrance, go up to the roof then use the corridor to get back to our staircase and used the stairs to quietly walk down the stairs to our level. There were a few times when neighbors were near so I had to hide, one time I hid in the garbage bin storage room until they left
The other method was to cover up women's clothes by a layer of men's clothing and bring the shoes and other clothes and shoes with me in a bag, in this case I didn't have to sneak out late but then I had to change elsewhere.
I used three places for that, the first was the bike storage at the floor level of our apartment building.
In that case I have never entered left or entered the building through our own entrance, always used the corridor at the floor level to go the neighboring staircase.
Other times I went to my garage and dressed up there, mostly in my car or in the rented storage room near the garage and ventured from there. That was even better because fewer people knew me there and they were already asleep by the time I got there.
