Did some searching. The descriptions seem kinda varied. But one review had it described as:

"described by Wright as “practical” and sort of looked like a G.I. Joe military exoskeleton. His face is entirely covered with some sort of apparatus on his mouth."

Which kinda sounds like the image I attached. Which I found on an article written earlier this year talking about how the film could be appearing soon. But, another description has it like this:

"The costume looks a lot like the IRREDEEMABLE ANT-MAN costume
•The face is completely covered, so we don’t know who the actor is
•It’s a black suit with red highlights"

And here's the last description I can find. Sounds more accurate considering they were rather detailed with what the footage was:

"It’s a mix of silver and red and instead of being an open helmet like the classic version - it’s much more insect-like and more like that Scott Lang/Eric O’Grady Ant-Mans than Henry Pym. "

So, there's a few that may help you come up with something. The footage was only a couple minutes, and he was shifting sizes a lot in it, so I think no one really got a good enough look is all.
