Looking at these two teasers side by side makes you think about A LOT like it is crazy how much can change in just two years. I mean the direction of the group everything from the styling, makeup, music, it's all so different now.
I'm aware this happens to a lot of groups not just katseye who are still finding their sound in the beginning and it's also common with some big pop artists as well. it's just crazy to look back and be like "woah, a lot has changed". Sorry about the repost it was glitching for some reason.
