The first lady prepared for her final year with style.

For President Barack Obama’s final State of the Union address, Michelle Obama looked radiant in a marigold wool crepe dress with a fitted bodice and slightly flared skirt by designer Narciso Rodriguez.

According to reports, the sleeveless banded dress sold out online before the end of the night. It originally retailed for $2,096 at Neiman Marcus, but could also be found online for around $628.

The 51-year-old first lady famously wore Narciso Rodriguez, the son of Cuban parents, when the president was elected in 2008. She also wore the designer at the 2009 State of the Union Address.

Past designers who dressed the first lady for the annual speech included Michael Kors in 2015, Azzedine Alaïa in 2014, Jason Wu in 2013, Barbara Tfank in 2012, Rachel Roy in 2011 and Isaac Mizrahi in 2010.

In the past, Obama has opened up about why fashion is so much more than which clothes people wear.

"Fashion is really about passion and creativity. Just like music or dance or poetry, it's what drives you," she said during a fashion workshop for students at the East Room in October 2014.

"It's what gets you out of bed each morning – she added – it's what you write about in essays in school and what you read about in the news. It occupies every ounce of your daily lives. I know this because with creative people, that's what their passion does — it makes everything else worthwhile."
