It was happened to me last December upon attending dawn mass. It was first day and I was so excited to hear the mass. I dress up very quick on my Sunday dress attire since my family waiting for me down stairs. (late sleep that night grrrr). In the church before the mass begun, I feel not comfortable. S**t!! I forget to wear my bra.
Luckily, it was not so obvious since my dress have a thin padding on it. I just hide it sometimes with my hand fan when I noticed unsolicited stares on my bump. It was a shameful experience.
How about you girl istoryans, have you experienced going outside without undies?
