what size should a sixteen year old wear? I wear a girls size fourteen now
I agree with Shawna. People aren't one size fits all. It depends on your heredity, bone structure, height, etc. What's most important is being happy with who you are and loving yourself. If those things are true of you, then size doesn't matter at all. If you feel good about yourself, then others will respond to that as well.
I'm going to assume you're talking about a dress or pant size. Let me know if I'm wrong. If that's the case, there is no set size you should be at your age. People are all different shapes and sizes. As long as you feel comfortable in your own skin, then there's nothing wrong with being any size.
It depends on what article of clothing you're talking about, and your height.
Hmm... it depends on what your style and personality is.
shoes.. pants.. what?
