You are pretty just as you are! And trust me, most people don't even notice things like that and physical appearance (AHEM LIKE ME). For example, didn't know one girl in my class wore glasses until she came to school without them and someone told me.
If anyone has a decent mindset at all, they won't care even a tiny bit, so try your best not to worry about it!
Honestly, just try to love yourself and have a positive mindset! Thinking about things from a different view can change your whole perspective on something! To love yourself is also to accept yourself! Accept you are a wonderful person, and know that you are perfect as you are.
