From GameTrailers:

Uncle Gary is back with a street lesson about the ladies of Stillwater.

From joystiq.com:

Capcom has released the "Femme Fatale," a set of alternate costumes for the ladies of Street Fighter IV . The DLC is the second in the alternative wardrobe series, following the "Brawler Pack," and will set fashionistas back 320 ($4) on XBLM, and $3.99 on the PS Store.

Having watched the first two minutes of Capcom’s video showcasing the outfits, only one thought comes to mind: Moar liek booty pack, lolz. Check out the video after the break.
