Kayla Miyamoto, along with her parents William and Nikki and her sister Zoe, debuted the costume at Wondercon Los Angeles on March 26th.
Here's a close up of the awesome costume, along with Kayla giving a BB-8 thumbs up.
The family lives in Los Angeles. William is an an actor and prop maker and Nikki is a costume designer/artist and both big fans of costumes and cosplay.
Kayla's previously gained attention for her R2-D2 and predator costumes.
According to William, the BB-8 costume took around 20 hours to make and his daughters came up with the idea for the costume.
"We will watch a movie or play with action figures and dolls and they say, 'I want to be this or that.' Nikki and I ask ourselves, 'can we make that? Or how would we go about constructing it,'" he says. "And then we just start."
