How would you pack for a Mediterranean vacation full of movie premieres and scenic strolls? If you're Selena Gomez, it would involve a suitcase stuffed with sheer fabric, plunging necklines and leg-baring skirts.

During her long weekend at the Ischia Global Film and Music Festival in Ischia, Italy, Gomez, 21, opted for sexy looks like the black Kayat gown with crystal detailing and Casadei heels that she wore on Saturday, July 19. The Spring Breakers star accepted the Ischia Kids Global Icon Award in the slinky gown that dipped low enough in the back to show off her fresh ink.

She switched up the look later that night with a LBD featuring an asymmetrical neckline and handkerchief hem, paired with Casadei pumps.

The pop singer's provocative looks were the latest in a parade of "come hither" ensembles. On Wednesday, July 16, Gomez set the tone for her Ischia red carpet style in a flowing L'Agence dress with a deep neckline and high slit.

Then, on Friday, July 18, Gomez wore the color-blocked shirt dress by Emanuel Ungaro to the premiere of her film, Rudderless. She unbuttoned the top and bottom of the maxi to create a plunging neckline and daringly high front-slit. Casadei heels and jewels by Ippolita and Tito Pedrini finished the look.

In between red carpets, the former Disney star covered up yet still managed to bare plenty of skin. On Friday, Justin Bieber's sometimes-girlfriend wore a floral-print halter dress with a midriff cutout by Zimmermann, paired with Casadei heels.

She chose the Australian brand again on Saturday, July 19, with its metallic floral-print romper and the same white strappy heels.

For a press conference on the same day, Gomez opted for the Blumarine sheer rose-embroidered shirt and matching tulle skirt with Casadei "Blade" pumps.

Gomez chose a sexy sheer lace romper by Zimmermann (yet again) for a boat cruise on her last day on Sunday, July 20. She added the edgy Brian Atwood "Abell" sandals to keep the look from becoming too sweet.
