Four of the outfits Lady Gaga will wear for her upcoming concert in South Korea were unveiled yesterday, including a leotard fashioned from guitars and a giant piano keyboard headpiece.

The US star will also show off the Giorgio Armani-designed costumes in four other venues during her Born This Way Ball global tour kicking off in Seoul, said Shinsegae International, Armani’s South Korean business partner.

The pop diva arrived in South Korea last Friday, a week before her Seoul performance which kicks off a tour of Asian venues and 21 European cities.

The new wardrobes, in line with the singer’s signature extravagant style, include a black bodysuit made of hundreds of glittering vinyl tubes sewn together with metal studs and glass pieces. Another skimpy outfit is made of nets and fringes decorated with scores of crystal pieces and and sharp spikes.

Lady Gaga, well known for outrageous styles and provocative performances, will also wear a long, skin-coloured latex tunic punctuated with triangular structures over her chest and face.

South Korea banned those aged under 18 from the much-anticipated concert − her second in the nation − after it was rated unsuitable for younger audiences.
