I love it when girls dress up and go to school or college. I did it too. It made me feel more mature. I was not trying to attract anyone. If you like dressing up for yourself then keep doing it. Others can think what they want. You are just dressing up for yourself. Nothing weird about that.
Its good to see people who put a bit of effort in instead of looking like you've just rolled out of bed. Its a good self image.. granted there are some days when we all feel like just putting on the grub stuff. Everything in balance i guess.
