I always try to look my best. What you wear and how you wear it can be a great way to express your individuality and creativity. I have a co-worker who always comes to work with her hair& makeup done and smells great. She is so pleasant to be around lol.
Tbh i dont really want to impress anyone except maybe that special someone. Also, i'm not always in the mood for using years in front of the mirror, doing my makeup and hair and putting together a cute outfit. Sometimes i like to spend a lot of time on my looks, other times i don't. I'm comfortable with that and i think it's healthy too. otherwise, sure i agree with you on the individuality and creativity thing, also looking good can make u feel good and that's why i like to look my best sometimes.
