Los Angeles, California – Billie Eilish seems to have shaken off her Bad Guy vibes as she has the time of her life dancing around with friends, with a drastically different fashion sense.

If her bleach blonde hair wasn't an indicator that the next era of Billie Eilish would be worlds different from what people have come to know, her latest music video is.

On Wednesday, the 18-year-old dropped the new video for her song Lost Cause – and the light-haired bombshell was almost unrecognizable at first look.

Dressed in clothing from Kim Kardashian's SKIMS clothing line, as the reality star confirmed on her Instagram Story, Eilish was surrounded by six women clad in the same attire.

For fans, and anyone else that's been paying attention to Eilish's fashion trends over the last two years, seeing the singer in anything but oversized t-shirts and baggy Gucci pants is an event in and of itself.

But the music artist meant what she said when she announced her Happier Than Ever album era would be nothing like what people have come to know her as.

In the newly-released video, which has amassed nearly two million views on YouTube in just three hours, Eilish shows off her curves in a major way for the first time publically.

In one scene, Eilish is dressed in a silky opened button-down and tank top, paired with SKIMS shapewear shorts, singing, "I used to think you were shy, but maybe you just had nothing on your mind. Maybe you were thinking about yourself all the time."

Between the twerking, video game-playing, and swapping out of different hats and outfits throughout, Eilish appears to be more comfortable in her skin than ever before.

During the pandemic, the paparazzi snapped a photo of Eilish in a skin-baring tank top and basketball shorts, causing some to claim that the young star might've gained weight during Covid-19 lockdowns.

But Eilish responded in the candid manner she's come to be known for, saying she's always looked this way, and that people just haven't seen her in anything but oversized designer apparel.

Her decision to now don more revealing outfits in her Lost Cause video might serve as a clapback to her haters and the body shamers of the internet.

But critics aren't the only one the singer is taking aim at.

The single itself appears to be her response to a love lost, that might not have been everything she thought it was. In the song, she sings, "I know you think you're such an outlaw, but you got no job."

As Eilish and her girl gang are seen in the new vid parading through a house dancing, playing Twister, and crawling over each other, she sings, "Thought you would've grown eventually, but you proved me wrong."

The debut is a steep contrast from any video during Eilish's previous When We Fall Asleep, Where Do We Go era.

Videos for songs like When The Party's Over and All The Good Girls Go To Hell have dark undertones and creepy special effects – like black ink running out of her eyes and large, dark wings emerging out of her back.

But quarantine seems to have brought out a different side of the Grammy-winning musician. All there's left to do is wait for her highly anticipated new album to drop on July 30 to fully understand the scope of her evolution.
