I'll half agree with you here. The "slim" look highly depends on the suit they're wearing. I think he looks really good in the second picture.
Now all of these look really good. I think that cut suited his body type well.
To me, the fit should also accommodate action/movement. When I saw the
opening of Spectre, I kept being drawn to Bond seemingly wearing a suit that
he had mistakenly shrunk by putting into the clothes washer (roof scene)...
The creasing and over-stretching kept having me think he'd split some seam soon,
especially at the crotch or back.
When (suit) material is too tight, it usually looks terrible after the action/movement
is done, leaving creases/wrinkles everywhere, like the disheveled look of a kid
leaving the playground.
The old Bond looked so cool, able to wear a nice-fitting suit/tux to a party, run
off to some side room to wrestle and dispatch some villains, and come back to
the party as if nothing (action) happened. The new Bond would look guilty just by
the wrinkled/torn clothing.
The same issue applies to (Standard) dance tailsuits, as in the other forum thread.
Action formal clothing are meant to look good either in or out of action. For
instance, dance tailsuits have specially designed shoulders and weighted tails to
ensure coolness (but not normal tuxes).
