The 23-year-old 'Hands To Myself' hitmaker - who began her Revival Tour in Las Vegas on Friday (06.05.16) - has admitted she was "completely blown away" by the silk muslin gown, which was created by the German fashion designer for her world concert.

Speaking to InStyle magazine about the ensemble, the brunette beauty said: "It makes me feel so badass. It's the best feeling in the world.

"[I was] completely blown away."

The 82-year-old creative director of the luxury brand Chanel spent 200 hours crafting the intricate embellished garment, which was embroidered with 12,000 pearls, beads and sequins for the black metallic finish.

The former 'Wizards of Waverley Place' actress is set to wear the show stopper, which was paired with black leggings and blue fingerless gloves, to perform six tracks during her eight-month long gig.

Selina was amazed she had the help from Karl for her costume designs.

Speaking about the collaboration, Selina said: "It's incredible because I'm in such a different place in my life ... It's crazy because now I get to collaborate with designers that I've aspired to work with and all of the looks are so distinct and beautiful."

And Karl is equally as pleased to have worked with the songstress.

Speaking about how he felt dressing Selena, he said: "[I'm] both happy and proud.

"I love her music, it's very strong."

Meanwhile, Karl recently showcased his Resort 2017 collection on the runway situated en plein air - the dividing line between the Old and New Havana - in the capital's Paseo de Prado, which was the first international fashion show in Cuba in over 50 years last week, following the recent union between the Caribbean island and America.
