[UPDATE: It looks like these alleged Spider-Man images are probably fake.]
The first few weeks of shooting for Captain America: Civil War took place on the streets of Atlanta, after which it seems production moved to a more confidential location inside sound stages and the like. As such, the set images have been sparse from Civil War of late, meaning fans will have to wait a while longer to get a closer look inside the film.
One particular element audiences have been craving for a look at is the new Spider-Man, who will make his debut in the Marvel Cinematic Universe in Civil War. Tom Holland is set to play the newest iteration of the web-slinger, who will have a minor role in the film before moving onto his own solo movies, beginning in 2017. Marvel Studios President of Production Kevin Feige previously revealed that this Spidey will be younger than the previous live-action versions - and we may (emphasis on may) have our first look at the new Peter Parker's costume.
BMD picked up on a Twitter account claiming to be the Russo Brothers - directors of Captain America: The Winter Solider and Civil War - who have been tweeting what appear to be behind-the-scenes images from the Civil War set. The most interesting of them all is one that may be our first look at the new Spider-Man costume (see below), which harkens back to the character's original look in the comics:

The texture on the suit is similar to most of the other superhero costumes used in big blockbusters nowadays, but the biggest surprise from the tease - if it is indeed the Spider-Man costume - is evidently the color scheme. Most modern takes on the character use the standard combination of red-and-blue to make up Spidey's suit, but this one is red-and-black instead. However, when Spider-Man made his first comic book appearance in Amazing Fantasy #15 in 1962, the hero sported the red-and-black look, just like this version. Could this be what Feige meant, when he indicated the new costume will have a "classic Spidey" look?
Another interesting tease from that very same Twitter account is the following image, which shows what appears to be a goggle atop some red fabric, perhaps offering a look at the Holland's Spider-Man mask (see below). If so, it seems Spidey's new eyewear could allow the character to be more expressive while in the suit.

Bear in mind, there's a fair chance that the Twitter account is a fake, as the Russo brothers used a different Twitter account before for the release of Winter Soldier. Plus, even if this is the diretors' new account, the pictures aren't clear enough to offer complete assurance that this is in fact part of the new Spider-Man costume. Fingers crossed, we'll find out for certain, sooner rather than later.
UPDATE: Guardians of the Galaxy director James Gunn is saying the Twitter account in question does not belong to the real Russo Brothers:
