US President Barack Obama was making serious comments about the Islamic State's threat, but the Twitterverse was obsessed with his tan suit.

President Obama held a news conference on the threat of ISIS in Iraq and Syria. Within minutes Twitter was lit up with comments on the crisp tan suit he was sporting just days before Labor Day, which fashionistas deem to be the cut-off point for wearing white and other light colors.

The White House response: "He loves that suit."

We can't really grasp the significance of colour and Labor Day in New Zealand, but either way we think the president looks dashing as usual.

Obama: Something something tan suit something tan tan tan something suit.

More than 4,000 tweets were posted about Obama's suit during that press conference

Remember that time the president wore an ill-fitting tan suit at a press conference?

I see no problem with the suit.

*20 minutes earlier* OBAMA: I'm not wearing this suit, Joe BIDEN: No, no you look great OBAMA: Fine. But I'm not wearing the Sea World hat

This is about more than a suit...!

For the astute fashion observers, Obama has worn a tan suit before. Here he is on Easter Sunday 2014.

The outfit now has it's own parody account with the handle of @BarackTanSuit.
