Affiliate Marketing Secrets

I’ve always wanted to be a model, and photographers used to offer to make me portfolios, and all that stuff.
Here’s the problem: I don’t think I can fit into any niche. I’m 5’5, which everyone says is too short to be a regular model, and too tall to be a petite model. Is that true? Same goes for my weight. I weigh 140 pounds, which is way too much for a regular model, but not really enough for me to be a plus size model.
And I don’t have pictures, but I have long curly brown hair and brown eyes.
