We have been accustomed to horribly undersized men's coats and clothing for over a decade now. The shrunken suit and menswear trend that Craig and Skyfall helped popularize was such a horrible, horrible thing.
A full length overcoat like that is actually far more practical of a garment than the shorter, tighter overcoats that have been in vogue for a long time. The longer length actually protects your legs from the cold and the fuller fit lets you layer more warm clothing for when it's really cold. However, the oversize thing isn't my style personally. For me, the gold standard is a beautiful well fitted full length overcoat like what Durrant gave Bruce in The Batman.
It's funny, Craig pushed so hard for the skinny suits and tight fits in the Bond films to look and feel younger and more modern and I have always just thought it made him look older if anything. He looks much more stylish with the more elegant, fuller fit stuff they gave him in Glass Onion.
