President Obama and First Lady Michelle took time out of their busy day to show the world how handsome, smiley and generally perfect they are at yesterday’s Congress picnic on the White House’s Front Lawn.

Michelle looks fabulous as usual, sporting a green summer dress with yellow color-blocking. But who is the lucky designer who created it!? So far, the internet has been unable to identify the brand–us included.

The First Lady has a pretty awesome track record of making the careers of emerging designers (Just think of what she did for Jason Wu at her husband’s inauguration) so whoever she’s wearing is probably going to experience a huge jump in sales soon. Then again, she could be wearing a new high street favorite–her love for J.Crew, H&M and White House Black Market is well known. Either way, whoever made that dress is probably one happy camper today–as soon as he/she/it comes forward.

So, gumshoes, does anyone know who made that dress? We’re putting on our detective hats to try to find out too. Stay tuned…
