Re: Doctor Who?...
Also, was it ever explained why the "Silence" aliens all wear rumpled suits?
I'm guessing it's to make them look extra creepy. The makers of Doctor Who seem to have struck on this fantastic truth that combining something freakish and alien with something familiar, dull and ordinary makes it even scarier and more creepish. ("Are you my mommy?" Though nothing about that was alien in appearance.)
=edit=
I suppose one answer would be because they can't wear normal T-shirts, and the V necks that would fit over their heads would have to be cut down to their navel. :p
