How to dress a 15 yr old hourglass figure?

I'm a fifteen year old girl (well, an old fourteen) in the UK. I have an hourglass figure (36" bust, 25" waist, 36" hips) and I find it hard getting dressed! I normally have muffin tops if I try to wear jeans because I am a little afraid about wearing a skirt and I dress quite casually. I normally find myself wearing converse, jeans, a vest and a shirt and I want to accentuate my figure without looking too provocative or attracting the wrong attention. Thank you! :D
