Well, I indeed was able to get in touch with Lhanie, aka Island Girl. Unfortunately Lhanie didn’t have a tremendous amount of information, but she was more than willing to share what info she did have. Below are select quotes from several emails that I hope might be interesting in regard to the original process by which Ringo’s costume was created for Tombstone, as well as be helpful to creating a replica Ringo costume.
From Lhanie (edited and condensed by me):
“My involvement with the movie [started] with Peter Sherayko. He asked me to work with costumer designer Joseph Porro. Joseph [contracted me] to make shirts. I made about 300 shirts for them. I made the shirt for the character “Johnny Ringo”. The dragon, Joseph had made to be embroidered. He sent me the bib part with the dragon and I made the shirt to complete the shirt. The ‘cowboys’ shirts are the ones I made. Joseph used them for all the actors except for the principal actors; (Kurt Russel, Val Kilmer, Sam Elliot and Bill Paxton).
I didn’t [make] the red sashes.
Since I moved [to the] East coast, I left all my sewing business behind. I am no longer in business.”
“I can tell you a little bit about the material on red sash. We use “crepe” type material. Anything that is a little medium thickness with some texture will do. Of course, fire engine red. Any kind of tassels or upholstery tassels for the edges. 5 inches wide and from 2 1/2 to 3 yards long. There are different kinds of red sashes that they actually use in the movie.
Johnny Ringo’s shirt is cotton, medium wt. Color is kind a bluish gray. All shirts that I made for the cowboys are based on the same pattern shirt. We only [changed the] ‘bib’ style, including Johnny Ringo. The closest one that Joseph and I used [is also] the one that Michael Biehn wears on “Magnificent Seven”. We used the same style bib-shirt.”
