Until recently I've been the opposite, not wearing a bra during the day but wearing a "sleep bra" during the night (probably similar to a bralette).
Now I mostly wear a full cup lacy underwired bra during the day and a sleep bra overnight.
@Denice - Male, female, other, I'd say that was unwanted physical contact. Though I personally have the safety net of being retired so my livelihood is not dependent on having to "grin and bear it".
