SBMAlso regarding clothing. Do none of you have teenage boys? Seirously, I would bet it was 100% lazyness why they didn't change. Gamers especially (ones I have known) spend days in their rooms without showering, changing, etc. Not just gamers though, teenage boys, and guys in their 20s. Not showering or changing their clothes daily is really common, disgustingly lol
My roommate in college was a gamer and her male gamer friends were absolutely disgusting hygiene-wise.


That being said, Bryer and Kam have always looked pretty clean in any picture of them that I've seen even from before the crime spree. And in the store footage, their clothes--and their hair and faces--look clean, and as mentioned before, they apparently did change clothes because the constables reported they were in different clothes the next day.

I don't think either of them were neat freaks, especially based on the dumpster they turned the RAV4 into, but I think they might have been particular about their appearances.
