Michelle Obama's State of the Union dress designed by Jason Wu

Michelle Obama wore yet another Jason Wu frock to President Barack Obama's fourth State of the Union address Tuesday evening, cementing the first lady's penchant for the American designer responsible for both of her inauguration gowns.

She accessorized the sleeveless (she's still showing off those toned arms) oxblood-and-black design with an Alexis Bittar flower pin.

The first lady's incarnation of the dress, described by a Jason Wu rep as "a red organza tweed flounce dress from the pre fall 2013 collection," looks a lot different than the runway version below (via Glamour):

Obama's repeat choice of Jason Wu left fashion bloggers wondering why the first lady wouldn't want to give another emerging designer the opportunity to showcase their talents on the national stage.

"Nothing against Mr. Wu — how could there be when the dress was this gorgeous? — but we haven’t seen a first lady give a designer this much exposure since Nancy Reagan met James Galanos," The New York Times' Eric Wilson wrote last month after the inauguration.

"The dress she wore to Tuesday’s State of the Union was edgier than the sweet dresses she’s commissioned from Wu in the past—a sign of their potentially strengthened alignment," The Daily Beast surmised.
