The chest and abs region, in particular, look to have been tweaked quite a bit, and Barry’s belt has finally been converted to an all gold color similar to the suit worn by Future Flash last season.
The gold boots from the original DC suit are still nowhere to be found, but considering how much this suit has changed to more closely resemble The Flash of the comics, they could be coming sooner rather than later.
Just going off of what was seen in the video, it looks as though the new suit features a lot less mesh and a lot more leather.
