So I just noticed how crazy I dress and that I don't even care XD To give you an example, at the moment I am wearing a Pokemon cap, a blush color tank top with an orange long sleeve work out top, a short skirt with leggings, and a little mascara with green eyeliner (to bring out my eyes).
I used to date a girl who wore exclusively neon and rainbow colours. And she never even wore em to match! It was like, bright pink chinos and a bright orange shirt and a bright purple jumper and a big red jacket, all at once. So much noise! I used to bug her about it but it didn't bother me or anything. She was a lovely girl, and she could dress however she wanted.
So don't feel secure, but maybe you can make sure the colours look good together >< I like:
