As an aspiring model myself, I know how hard it is to grow in this industry without representation. It is like searching a needle in a haystack to get updates of the latest go-sees or auditions for you to start up with. This is usually communicated through modeling agency. Clients contact several agencies or talent scouts to get their models. They don't usually post it on the internet, or advertise it on TV so it will be hard for models without agencies to score an audition.
If one wants to succeed in the fashion industry, he/she usually goes to Paris, London, or New York to fulfill his/her dreams. Going there is just the start. Competition is steep. It is imperative that you get someone to help you succeed. There are hundreds of different agencies from around the world but if you want a Central London location, professional advice, and has industry experience, UK Models is the one for you! You can register from their website for free to be reviewed to be one of their models. They accept different kinds of models and assure that their talents get impressive portfolios. Choosing the right agency for you will be a good start for your career.
