If the amount of promotion Selena Gomez has been doing for 'Spring Breakers' is any indication, the movie should do well when it lands at the multiplex, since the singer/actress is promoting it at every turn.

After a whirlwind European promo trip that saw her showcase her style in Gucci and Dolce & Gabbana along the way, Sel revisited one of those designers as she hit up the SXSW Festival, which commandeers Austin, Texas this week, with her castmates to hawk the film at its March 10 premiere. Of course, she looked beautiful while doing so.

While Vanessa Hudgens had to bail on SXSW due to illness, Gomez and castmates  Rachel Korine and new brunette Ashley Benson were there in full effect.

Sel was brightening up everyone's day and the room in her Dolce & Gabbana ensemble. The bright orange skirt and flowered, bikini-style top, which showed just a hint of her tummy, were a pretty pairing, thanks to the pencil shape and the star's curvy figure.

But the back was equally as sexy, with the knot and the eyes on the shoulder straps. See 'em? Overall, the styling was very resortwear. And did ya check out Sel's bootay? That thing is bodacious. We see Spanx, too.

Sel's long, thick hair fell in waves on one shoulder, like a cascade worthy of Rapunzel. She matched her lipstick to her skirt, choosing a coral shade, keeping it all in the same color fam.

Gomez hardly looks like she is bumming over her split with Justin Bieber. But then again, she is focused on the task at hand and that's helping to make a movie where she sheds her good girl image a success.
