The 38-year-old singer surprised all her fans twice, because last Sunday night there were two events marked in red for the American singer’s agenda. The first was the finale of the television show ‘American Idol’, which ended its 21st season with the closing. Katy Perry has been the judge of the show for many years and chose a dress that took the breath away from all viewers. An elegant orange dress with the signature of Giuseppe Di Morabito and risky to go on television that did not hesitate to share with all his followers. Later, at the party after the gala and in honor of another season of ‘American Idol’, Katy Perry chose a riskier dress that did not go unnoticed. The singer left little to the imagination when she wore a long black Alaia dress, but with some transparencies that showed her underwear. The dress is from Alaia and she combined it with strappy heels and a black handbag. The dress in total is priced at 3,180 pounds and social media hailed her look on Sunday night. The party, held in Beverly Hills on Sunday night, was the date chosen by the singer to wear the dress. The singer rose to fame in 2008 with her famous song ‘I kissed a girl’ and ‘Hot N cold’, both belonging to her debut album ‘One of the Boys’. On the show ‘American Idol’, the singer began her participation in 2001 and has been on the air for more than twenty years and in prime time.
