Thick Beanie in 90+ degree weather that clashes loudly with a suit that you shouldn't be pairing with any beanie in the first place. 
Suit either poorly fitted or not tailored to fit at all.
Ultra Casual suede loafers that also clash loudly
Buttoned up bottom button 
Best of all, Tim has this look that betrays that in his own he's absolutely slaying it with this look. I'd put money on a bet that the suit is probably from some over hyped designer brand (likely Armani because ...... Tim).
It is very silly to have a button you are never meant to button. I will never understand fashion.
The east German military coat I'm currently wearing is double breasted, but the left line of buttons is for symmetry. The left side of the rear flap is held in place with a hidden button.
Gives me hips tho
It is my belief that things like this exist for plebs to out themselves as not belonging in high society.
