Barack Obama's post-presidency style called 'too casual'

Obama's newfound casual style has been a topic of conversation since he left office in January. Everyone loved seeing him kick back on vacation in February, and when he stepped out in D.C. in March in a brown leather jacket, a grey button down shirt, belted jeans and a SCOUT bag, he was officially deemed a "cool dad."

However, now that the former POTUS is stepping back into the political spotlight, some are arguing his style should be reflecting that. While he accepted his "Profiles in Courage" award in a classy tuxedo on Sunday, he appeared at the Seed & Chips: The Global Food Innovation Summit in Italy on Tuesday in much less formal attire -- and GQ has a problem with it.

Take a peek at his arguably informal look:

Rather than leaving two buttons of his collared shirt undone, GQ would have preferred he wore a tie -- or at the very least, only leave one button undone. As they put it, "Fabio would be proud, but us? Not so much."

Now, when Obama stepped out for a "power lunch" with Michelle and U2 frontman Bono in March, no one seemed to have a problem with his relaxed, unbuttoned look. But what we think GQ is trying to say is, there's a time and place for everything -- including leaving "a whole lot of open real estate in the chest region."
