Wearing a corset on over your clothing while pregnant should be considered NVL.

Some pregnant women in the 1890s did wear corsets, but they were maternity corsets and they were not made of the material that the available corsets in game are. While obviously pregnant characters can say that ICly they are wearing a ‘maternity corset’ under their clothing, as was relatively standard, it is absolutely inane and just gross that people are wearing full on tightly laced corsets while roleplaying as a pregnant character. It’s very RDO and it, to me, seems to be NVL and totally unimmersive.
