In 2012 Erika Hicks moved to New York City, intending to hone her skills as a designer in one of the fashion capitals of the world.

After acquiring six sewing machines, three dress forms and an abundance of fabric and trim, Ms. Hicks realized the space she could afford in Brooklyn wasn’t going to work.

She tried Harlem as a home for her and her designs but couldn’t find the inspiration she needed. Then she headed across the Hudson River and visited Newark, N.J.

“There were leather studios, embroidery factories, and garment construction booming in Newark.” said Ms. Hicks, who is 29 years old.

She quickly found a home there, joining a growing group of designers who have forsaken ateliers in New York City for Newark’s lesser-known fashion community.
