the movie itself is, and thats my opinion, utterly flat and uninteresting if you leave out the manners and suits.
this suit isnt!
grey flanell, simple, 2-buttons.
easy to combine to brown and suedes.
with flanell suits you even might try non-silkes ties, like cotton e.g. as long as still kept simple altogether.
stuff I also wear:
ST Dupont cufflinks, Versailles limited edition-more later
Omega watch, "vintage" and my grand-pa's-more later
Ascot tie in black watch.
white PS (=Pocketsquare) which is invisible here.
