Thanks to LL member Jackson in this thread, here's a short TF1 video clip of the French tailoring house of Camps de Luca featuring head cutter (chef coupeur) Mario Valente and tailors Marc de Luca and Charles de Luca. You will see an example of the cran Necker notch style in the middle of the clip when Charles de Luca pulls out a jacket made for French singer Claude Francois.
