When would using a visible zipper on a costume be a problem in a play or film with a historical setting? When the zipper color does not match the costume color
When the actor does not like zippers
When the play or film takes place in a time before zippers were invented
When the costume budget is low

When the play or film takes place in a time before zippers were invented

Explanation:

If the play is in a historical settings, zippers were probably not invented. So if you had a zipper on your costume it wouldn't make sense.

Hope this helps!
