lmao in what world are you living? You cant age so much in just two years. Tzuyu still has a lot of time on her plate.
The irony is that you are comparing her with 2019 pictures when there is less to no difference in her face with nowadays. The problem is the make up and hair style. An example of how bad it is now:
She is a super pretty girl and in the top three of Twice's visuals for me, it's just that her styling can be a miss sometimes. For example her eyebrows, she had such perfect natural shaped eyebrows that gave her face sort of an edge, and now they changed that to make her look more soft (?). I don't know if I'm making sense but that's what I noticed. She is still gorgeous though.
You chose the worst pics with harsh lighting. The make up artist also gave the entire group a more mature style, outside of the stages she looks the same with a bit of maturity. But don't worry though, even if everyone in the world forgot about her, we know you won't.
She's still pretty, but other members are catching up to or even surpassing her beauty, especially the J-line who glowed up immensely.
The fundamental difference is, at Dec 2015 she was going to take over the entire Asia, but now no one talks about her while the It Girl position was taken by the Senior Singer of KPop.
yeah I agree, those brighter colors just dont suit her also like many people said, makeup is often not the best on her.. those Makeup Artists serioulsy deserve punishment for what they are doing sometimes
They start to fill out into their adult bodies from around 19-22. It especially noticeable in their face as it gets chubbier. It's not unlike the Freshman 15. Also companies are less strict with idol diets after a 1-2 years after debut.
