As a seamstress who does tons of online shopping, though I'd give this epic Google hunt a go.
Closest fabric I could find was an upholstery velvet, but the white is beige and the stripes are off.
Here.
Tried tons of search words - black, white, blue (in case that turned up a decent match), velvet, velveteen, velour, towel, terry cloth. Stripes are tricky to match and that particular stripe variation more so.
In the end the closest I could find was - the one
you can get at Target. And it's a Deadpool one, def a movie tie-in piece, though not perfectly accurate? And you'll have to take the patch off, there's no breast or hip pockets that I can see, and the cuffs and belt are black and not same-fabric. Lastly, they went a lazy route with cutting the pattern. On Deadpool's you can see the left chest side the stripe colours go red-black-white and the right side is reversed. Oh well.
The stripe pattern is the best and closest I found and I guess if you have coupons or whatever you can get two and fix the cuff/belt and pocket situation? If it's terry cloth with no discernible nap, you could take the back piece of the second and recut it to be the right front piece so the stripe colours face each other correctly. Assuming you don't mind paying for two robes, anyway.
Edit: I just noticed it's an in-store item only, so you would have to trawl a Target near you or call around. Not as convenient as online shopping, sorry, guys. Maybe one kind-hearted RPF member who has access can pick some up and pass them on to people interested for shipping and a handling fee?
Good luck, Deadpools!
