I am a high school teacher, and wardrobe malfunctions are not easily forgotten around here. I'm screwed.
I'm a teacher, too (Middle school) and I am constantly worrying about my boobs popping out of my clothes. I had to retire a couple of shirts already that were a little too low cut for my new rack. I haven't noticed any staring yet...
Luckily I've lost a bunch of weight due to m/s, so that's balancing out any bloat. My pants are kinda huge on me at the moment, but I figure I'll make it up fast once this nausea kicks off.
