Re: How long before TNG were the Wrath Of Khan uniforms phased out?
They wouldn't need to design new costumes, just sew new versions that fit the aging actors. Certainly Jimmy Doohan didn't get forced into an ill-fitting costume from the 1960s, or even the early 1980s when he needed one, did he?
What was being discussed earlier was designing all-new costumes for everybody.
