All 65 of their descendants had to turn up for the birthday party on May 20 with their friends.
The twins were featured on a local news report when they caught the attention of 28-year-old photographer Camila Lima.
“I photograph many young couples, so my love for photographing older couples is a way to inspire younger couples,” Lima said.
The photo shoot, which took two hours, included everything from hair styling to make-up application and matching dresses.
“They did everything I asked and did not complain about tiredness,” Lima told ABC News adding that the twins were “very happy and satisfied” with the final product.
