Here are some things to consider.
Every girl wants to be a model one time in there life, however, the modeling industry has STRICT requirements.
Are you 5'9 or over?
Are you in between 100-130 pounds?
Are your measurements around 34-24-34? Only 2 inches can be apart
Are you uniquely beautiful? And not just another blonde ir brunette?
If you are below 5'9, there IS editorial. So don't worry.
Its very hard to break in though. Its brutal, cold-hearted industry that eats you alive. I was once told I was "hideous" and "ugly" right to my face. You have to be not only beautiful, but STRONG and you have to know that "no matter what people say, you are who you are, and your beautiful in your own skin"
Try looking around in your area. Search "modeling agencies in _____(your city) on google.com and see what you find.
:) good luck
