P to the S

I am growing my hair out but its at the terrible awkward stage where I can't do anything with it and it looks like mom hair. I'm growing it out like victoria beckham. It will be short in the back and longer on one side. Its very cute and chic. I'm thinking about getting extensions, what's everyone opinion on this issue. Good idea? Bad idea? Worth the money? Beaded? Sewn in? I have no idea. :(
