In the final snaps, the Ocean Eyes singer snapped a mirror selfie selfie in a green Coach zip-up jacket, followed by another selfie highlighting dark eyeliner and her matching black tresses, which were styled in two high buns.

The newest social media post comes after Billie clapped back at critics of her style evolution since the start of her career.

On May 27, the Grammy-winning artist took to her Instagram story to hit back at the haters who have branded her a "sellout" for adopting a more feminine sense of style over the years.

"I spent the first 5 years of my career getting absolutely OBLITERATED by you fools for being boy ish and dressing how i did & constantly being told i'd be hotter if i acted like a woman," she said. "Now when i feel comfortable enough to wear anything remotely feminine or fitting, i CHANGED and am a sellout."

After revealing that she's deleted her social media apps off of her phone, Billie certainly seems to have found a fitting middle ground as she continues to proudly show off her unique style.
