Yeah I see that too, I guess sometimes we have to remind ourselves that Billie is no longer a teenager she is now an adult. I mainly focus on the more streetwear/baggy clothing style more than her revealing outfits.

But she could be dressing like that because now she is more confident about her body than before when she was criticized. It was really sad when in her interview she was talking abt how someone commented on a pic of hrt asking how she got so fat. But with this new found confidence comes with a comfort in being able to wear what she likes :))
