Note a wider peak lapel with a narrow tie and the working buttons on the sleeve.
Wider lapels have been popular in streetwear style blazers for at least 2 seasons now (check out Wrangler 47's western style blazer, for example.) A nod to the Seventies (again). And nearly everyone has working sleeve buttons and single breasted peaed lapels, down to second tier designers like Kenneth Cole, for at least one season. As for the peaked lapel design, I have a 4 or 5 year old Emporio Armani single breasted peaked lapel suit that shows that that man saw it coming, as usual, well before the madding crowd. Same with the resurgence of 2 buttons, which have been staple at Emporio Armani for at least 2 full years now. The man is getting old, and his collections have been hit-or-miss for a while now, but let's not forget that he is still the maestro.
