Olivia Rodrigo's Daring Guts Tour Wardrobe Boasts Hot Pants, Crystals and a Nod to Gwen Stefani

Olivia Rodrigo was built to be a fashion icon. 

We're only two months into the year, but the "Vampire" singer, 21, has already given us plenty of style inspiration for our mood boards — and she isn't done slaying yet.

On Feb. 23, she kicked off her Guts World Tour at the Acrisure Arena in Palm Springs, California, and rocked out in a handful of edgy, skin-baring looks that have only cemented her pop star status.

With Guts, Rodrigo's sophomore album about bad decisions, love, heartbreak and self-reflection, the Grammy winner has committed to a grown-up version of the punk Y2K aesthetic she's been formulating since her Sour era.

She brought the same energy to opening night of the tour with her most daring looks yet. To paint the picture, Rodrigo belts her heart out wearing only a bra and hot pants at one point during the concert.

Her outfits are so good, we needed to break down each one, starting with this:

This blinding one that literally sparkles like a Twilight vampire in the sun. Rodrigo riles up her audience with head-banger "Bad Idea Right?" and we can all agree that having this set in her wardrobe was one of the best sartorial decisions Rodrigo's ever made.

Stylist and costume designer Heather Picchiottino sourced Rodrigo's custom Swarovski crystal mesh bralette and skirt from Michael Schmidt Studios. It's reminiscent of the singer's Ludovic de Saint Sernin VMAs gown, which was encrusted with 150,000 crystals from the high-end jeweler.

Then she goes a little darker with her style. Against a sea of backup dancers dressed in ballerina pink, the singer can't be missed in her black sequin bra and high-waisted hot pants (the risk-taking moment we were talking about before).

No great concert is without a quick-change and Rodrigo transforms her all-black look by throwing on a Rabanne minidress-style slip strung with see-through embellishments.

Rodrigo's sexy side comes through even louder with this plunging red jumpsuit, which screams '80s rockstar (Rodrigo's pleated-skirt-to-hot-pants pipeline will be discussed another time).

Picchiottino's custom-made ruby red one-piece, which is styled with ripped stocks speckled with glittery stars, makes perfect sense for Rodrigo's guitar jam session.

Rodrigo wasn't alive when No Doubt released "Just a Girl" in 1995. Yet here she is, nearly 30 years later, bringing Gwen Stefani's famous "I'm just a girl" feminist slogan to the spotlight again with a $20 tank top from online retailer Phantasy, which specializes in all things baby (as in Gen Z's favorite preferred way of saying "shrunken crop top").

It's all the more fitting because Guts is Rodrigo's love letter to girlhood. Across all 12 songs she belts, screams, and melodically sings about insecurities, growing up, idolization, beauty standards and, in this particular instance, fantasizing about getting back with her ex while simultaneously plotting his downfall for sweet, sweet revenge.

Stefani and Rodrigo may have 33 years between them, but both understand what it's like to be a girl — it's messy, romantic and sometimes you just need to rock it out.
