Three-dimensional imaging technology, often used in medicine, is being embraced by a small-business owner in Troy to make bras.

Hannah Johnson is an engineer by training, but a clothing designer by trade. For Johnson, it’s all about comfort. Johnson is the owner of Zebra Bras.

Holding a special camera attached to an iPad, Johnson explained how the technology works.

“It uses the built-in camera on the iPad, plus there [are] two additional cameras seeing different wavelengths of light and two lasers,” Johnson said.

Johnson graduated from RPI and worked as a nuclear engineer for 3 years. She’s taken those problem solving skills and applied them to customer service.

“If something happened, we couldn’t just say 'we’ll fix it next time.' We had to figure out a solution right away. So I think that has helped me,” said Johnson.

Her store opened 3 months ago. Standard bras cost $75. Clients first book a consultation and fitting, then custom-fitted cups are created using a 3-D printer and hand-sewn into a bra Hannah. The process takes about one week.

Johnson also aims to serve members of the transgender community.

“It can be so uncomfortable to go in and even just go into the women’s section at a Target, so I want it to be clear that this is a place that trans people are welcome,” said Johnson.

Johnson hopes to someday open additional locations and train staff.
