NEW YORK (AP) - Mindy Scheier was working in fashion before her son, Oliver, was born with muscular dystrophy. As he grew, and she watched him struggle to get dressed, her eyes were opened to her industry’s limitations for people with disabilities.

At 8, Oliver wanted to ditch his daily sweatpants for jeans, favored by his peers. His mom couldn’t find any to accommodate his leg braces and difficulty working zippers and buttons, so she began making adaptations herself.

She put strips of fabric fastener on the inseams of the jeans, and she replaced the button and zipper on the front with the same. The difference to Oliver was immense.

Now, Scheier dedicates herself to raising awareness about the need for designers and retailers to embrace adaptive clothing through her Runway of Dreams Foundation and Gamut Management talent and consulting agency.

Scheier has brought on board some of the largest U.S. brands and retailers. While adaptive clothes, shoes and other gear have made strides in the last few years, more in the industry need to get involved, she said.

“What we learned was brands were so afraid to get into the space for fear of doing it wrong, saying something wrong, not knowing where to start,” she said. “We work with brands to guide them through the process.”

Oliver, now 18, is pleased with the progress, but he said melding fashion with functionality for his age group has lagged behind offerings for younger kids and adults.

“It’s all about opportunity and the chance for people like me and people my age to express themselves through fashion like any able-bodied person,” he said. “It says a lot about who I am on the inside, and adaptive clothing allows me to do that.”

It’s also about including people with disabilities in the design process, taking care to offer such things as hidden openings for medical ports, tubing and bags, or less bulk in the front and a higher rise in the back of pants for wheelchair users. Dressing without help is made easier with things like pull-on loops at the sides of skirts and pants, and wider necks on pullover shirts.

Shoes must be wide and sturdy enough on the inside to accommodate braces or prosthetics. Zippers or other fasteners make them easier to put on for people without full use of their hands.

Adidas was among the giants to work with Scheier. The company consulted Oliver and others with a wide range of disabilities on an adaptive backpack that has a flat bottom, wider loops on zippers, and straps that can easily attach to wheelchairs and scooters.

From Tommy Hilfiger to Target, brands and niche online sellers such as No Limbits and Billy Footwear are serving people with disabilities. JC Penney, Walmart, Kohl’s, Amazon, Uggs and Zappos also offer adaptive fare.

Walmart is among the newest entrants, partnering with brands that specialize in adaptive. The company is working to get prices down and including more styles for older kids.

“Tweens are, in my opinion, an underserved customer holistically today,” said Brandy Lackey, a Walmart senior director of product development who worked on the recent rollout.

The adaptations required are as diverse as the people in need, including those with sensory processing issues who require softer fabrics, no tags and no-itch flat seams.

Niche sellers are also seeing the need. A company called French toast, for example, sells a crisp white Oxford shirt with fabric fasteners hidden behind a line of buttons for young people required to wear school uniforms.

Billy Footwear was co-founded by Billy Price, a wheelchair user who broke his back at age 18 and had trouble putting on shoes by himself. His company offers a slew of trendy footwear with a zipper that goes down one side and around the toe, opening the entire top.

“Our goal was to be able to come out into the market with an easy shoe that could work for anybody,” he said.
