You do understand there are different types of models? The only modelling job that requires anything like an extremely thin body usually are haute couture / high fashion runway models. Do you even know what kind of model you want to be? Victoria secret models are a different type of runway model, but they are still models. Advertisement/Magazine models are a different type of model. Alternative models are a different type as well. So what type are you interested in?

Most of the information you gave me is irrelevant. Most need polaroids, you can send them in. What they are look for is good skin, interesting/striking facial features (jaw-bone, cheeks etc) . The only place your size really matters is in high fashion runway modelling like I said, but there are other types. Your pants size and shoes size doesn't matter. Your dress size doesn't matter (you won't be getting paid unless you're represented by an agency). Your thigh gap doesn't matter (many models don't have a thigh gap ), the thickness of your arm doesn't matter.

What you need is a portfolio. You need a few pictures of yourself without makeup or with very minimal makeup. You need to find photographers and pay them to do TFP/TFCD so you can build your portfolio, OR just go ahead and send polaroids to various agencies and see if they accept .

I'm closing this question because of your answer. You could've just said no.
