LOS ANGELES — One day, when he was 4 years old, Max Alexander proclaimed to his mother, Sherri, that he was a “dressmaker.”

And this was before his mom bought him a mannequin and taught him how to sew. By age 5, he had hosted a fashion show in his backyard.

“So, he had sewn like 50 dresses,” she said. “I mean, it was every day. He was making a dress a day. It was, like, crazy.”

Now 6 years old, Max has a healthy Instagram following, and his dresses fetch up to $1,200.
