Where can i find cheap nice ladies clothes for a teenage online? Australian sites, or sites that ship to aus?

So im a teenage, i hate spending all my money on clothes, cause i love them that much, and need more! So what sites could i use? Cheap dresses, skirts, tees? Please anyone? I've already tried ebay, never anything for cheap. Thanks! p.s im from australia, so aussie sites, or ones that ship there for a low price!
