Lauren Conrad... Total idol! Ever since Laguna Beach, i knew she was always in the know about everything fashion. She's worked up to where she is and i have everything she has written haha! Including the Bible that is 'Style' (amazon.co.uk from £7)
It gives you ideas on how to dress for loads of situations including interviews and first dates! It also includes make up tutorials and hair styles... I have used it so much, so worth the money!
