Oliver Queen is about to undergo a makeover.

When we last saw this superhero, of course, he was ditching the concept of being a superhero and driving off into the literal sunset with Felicity.

But when we see Oliver on Arrow Season 4, he'll be looking a bit different.

The series debuted his new duds at Comic-Con on Saturday. What do you think?!?

This new getup signals a major transformation Stephen Amell's main character

“We’ve always said the progression for Oliver is very much from the Arrow to Green Arrow,” executive producer Greg Berlanti said at the show's panel. “This is first real stop in that direction."

As for what we can expect when Arrow Season 4 kicks off on October 7? It won't suddenly be a comedy, but...

“When the season starts, he’s in much a better place. He’s happy. He’s in love," producer Andrew Kreisberg teased.

"That feeling infuses all the characters. There’s a little bit more fun [and] more humor.”

Check out the sizzle reel that played at Comic-Con and be sure to watch Arrow online if you need to catch up this summer.
