Yes - exactly.
The more usual form of the expression is 'be seen dead' as in
'I wouldn't be seen dead wearing those trousers.' (You'll never see me wearing them.)

I should have added as alternatives:
'I wouldn't be seen dead in those trousers' or
'I wouldn't be seen dead with those trousers on.'

You deserve to be called English Kungfu Master...retired but still powerful
"She wouldn't be caught dead with a quarter pounder."
Can anyone tell me what "caught dead with" means?
Does it mean she would never eat it?

Just in case you do not already know this (you probably already do),
many Americans use the word "pants" instead of "trousers." I hear,
however, that the word "pants" for British speakers means "underpants"
(underwear). I have read that some Americans who have visited the U.K.
have innocently said something like this to a British friend: "I like your
pants."
