This is the best screen capture I could get of Frank's wrist.   There seems to be 3 buttons of some kind on the inside of the wrist.  The seam runs down the pinky side of the gloves - common construction method and easy to find in patterns.  You'll want a fabric with some stretch, but it doesn't need a lot.  Vogue 8311 and Vintage Vogue 8608 both have nice styles, but neither are long enough.  You can find glittery fabric pretty easily around Halloween, or you might get lucky at a thrift shop finding a glittery top to cut up.  Knits may curl a little when you cut the fingers, but shouldn't unravel.  Make sure you secure all your stitches if you cut the fingers off anything.
