Seriously? I wouldn't recommend it. White dinner jackets are supposed to be for warm-weather events in warm or tropical climates. He is in NYC with snow on the ground. I think he is wearing penny loafers too. I also don't like the black vest peaking through the jacket. I think a cummerbund would have looked better. As for the lapel, I hope the reason I can't see one on the one side is simply poor photo quality.
I hope you at least plan on wearing the white dinner jacket in the appropriate setting.
