The long-awaited Spice Girls reunion tour kicked off Friday at Croke Park in Dublin, Ireland.
Melanie B, Melanie C, Geri Horner and Emma Bunton performed some of the group's most famous singles without former band member Victoria Beckham and set expectations high for the 12 remaining shows in their first tour in over a decade.
Although the group reportedly dealt with some sound issues throughout the night, which Melanie B later addressed and ensured would be fixed at their next stop, many fans and attendees of the stadium concert raved about the "Spice World" opener.
Check out some of the top moments from the night.
Their colorful costumes were back and better than ever
The singers wore bright, exciting looks onstage and switched outfits multiple times throughout the night.
Geri Halliwell, known as "Ginger Spice," shared a closer look at her look before the show, an updated version of the famous Union Jack dress she wore to the 1997 BRIT Awards.
The garment, created by costume designer Gabriella Slade, had 'Girl Power" written across the back. Slade worked with each of the singers to create a total of 24 looks.
One of Melanie B's performance looks was a leopard-printed outfit, while Melanie C wore a bright blue sequined two-piece at one point during the concert.
Emma Bunton, known as "Baby Spice," wore a hot pink, mini dress with a dramatic train before switching into her next look of the night.
"Oh my god! What fun we had! I can not wait to get back up there again in Cardiff tomorrow night!" Melanie C wrote in an Instagram post.
They brought out of the classics and fans went insane
The leading ladies knew it wouldn't be a reunion tour without a powerful performance of their 1996 hit "Wannabe," and they did not disappoint.
The set list for the night was also packed with other hits from the past, including "Spice Up Your Life," "Stop," "Mama," "Say You'll Be There," "2 Become 1," "Goodbye" and "Viva Forever," among others.
The group celebrated all of their fans
The Spice Girls have always been about bringing people together.
“We welcome all ages, all races, all gender identifies, all countries of origin, all sexual orientations, all religions and beliefs, all abilities,” the members of the group said at the beginning of the performance, according to Variety.
“Like a king or a queen, we celebrate you. But I’ve got to say, there are a lot of queens here tonight,” Horner said.
The group's next stop will be at Principality Stadium in Cardiff, Wales, on Monday.
