Ann Romney, Janna Ryan Shine At Republican National Convention 2012 (PHOTOS, POLL)

Ann Romney and Janna Ryan, the potential FLOTUS and SLOTUS respectively, struck two very different ensembles at Thursday night's Republican National Convention, where Mitt Romney finally accepted the nomination to be the Republican candidate for president.

Mrs. Romney, fresh off her own RNC speech for which she wore a dazzling Oscar de la Renta red dress, opted for another vibrant hue: robin's egg blue, in the form of a sleeveless dress, gold bangles, nude heels and (bold!) a sparkly spider brooch.

Janna Ryan, on the other hand, eschewed color in favor of a black sleeveless dress with a keyhole neckline and white piping and black pumps. On Wednesday, she wore an emerald green frock from Talbots.

We couldn't help but notice: both looks are faves of current FLOTUS Michelle Obama, who has well-documented proclivities for both blue and monochrome. (Mrs. O wore red and black for her family's big night back in 2008.)

But back to the Republican ladies: who looked better? Compare below!
