Most Helpful Girl
That's how I used to feel a couple of years ago, I used to just wear sullen colours like black and grey. It's a reflection of how you are as a person, I'm much happier now within myself than when I was 16. It literally just came with age, one step at a time and I began introducing more colour and girlier things in my wardrobe. Once you start trying new things, you just become more accepting anyway and should gain more confidence.
