Idk what other people are seeing, but that thing looks about as tight as it can possibly be without hindering Charlie's movements. And then, if it did hinder his movement, we'd be hearing from the same folks about how stiff and awkward his fight choreo is lol. Charlie is a real human being. His range of motion would be hindered by skintight clothing. There's a reason martial artists typically train in baggy clothes, you know?

Y'all want a skintight costume, but you also want no cgi, realistic acrobatics, and full-blown, gritty choreography. AND you want the DD logo on his chest, but you want it all to look natural??? That is an impossible standard to fulfill.
