What happens is you go to space and you become weightless. So far so good, right? But then your body expands??? But your bra doesn't—so you get strangled by your own bra.
Now I think that this would make for a fantastic obit—so I tell my younger friends that no matter how I go, I want it reported that I drowned in moonlight, strangled by my own bra.

And that, ladies and gentlemen, is why there's no underwear in space. Give 'em hell, my gorgeous princess with a blaster. Love you always. ♥♥♥
