Your reason for chasing a modeling career does not need to be complicated. You can keep your answer personal, or tell a story if you would like. Perhaps you grew up in pageantry, your parent was a model, or you grew up watching modeling shows like America's Next Top Model. Fun! Whatever your reason, keep it concise and confident.
"I have always had a keen interest in fashion, but never felt I was the right size or shape for typical modeling work. I was approached in my late teens by a talent scout and soon realized this was something I could pursue, as a full figure model. Receiving positive feedback from the small campaigns I have worked on has inspired me to want to continue this as a full-time career."
"I grew up watching TV shows like ANTM, and it inspired me to practice my walk, my posing, and try new looks. I decided to try my hand at modeling recently and have done a few shoots with photographers. I have tried bridal, athletic wear, and lingerie shoots. I love them all!"
"I grew up involved in pageantry, so I got a taste of posing, wearing great clothes, dancing, and winning awards, at a young age. I love the thrill of internal competition."
