Thoughts on F4

Yes. I bought the Fantastic Four movie (before my recent vow to spend less). I've watched it several times. I enjoyed it. Does this make me a bad Marvel Fangirl?

Anyway, I was thinking: their uniforms are impervious to heat/turn invisible/stretch because they were exposed to the same radioactive energy as them, right? But they were wearing some suits over them that didn't react (as far as I know). I put this down to the unstable molecules in the suits.

Does this mean that they also have unstable molecule underwear (which was exposed to that yet unidentified radioactive energy), or do they go without?

I have this mental vision of Reed making unstable molecule underwear and throwing it into the machine he made to recreate the storm.
