Costume Designer for Superhero promo

We're creating a promo for our showreel production company, and created a mascot for the brand that is a superhero. Influences in the costume and material (polyester/cotton over spandex) stem from the 60s Batman and Reeves Superman era. I've attached a photo of a rough costume design I mocked together, and would love to see it realised as close as possible to it!
