Honestly I wasn't expecting the zippers either, and it's definitely not something you'd notice unless you're looking for it very deliberately - but after many many years of cosplay I try to keep an eye out for things that seem out of place (which was the wrist zipper pulls - I thought they might be chains/bracelets or something at a first glance, and went digging). And it's always useful to try and figure out closures (and then when it's stuff that's drawn, proceed to cry inside when you realize the artist didn't bother to draw like, a front seam or anything)
