In this video, Izzy demonstrates how to adjust a bodice block pattern for prominent shoulders, a common fit issue where the front shoulder bones cause fabric to pull across the chest. This tutorial is part of a miniseries focused on individual fit alterations, emphasising that multiple adjustments may be needed for a perfect fit.

Izzy explains that prominent shoulders create drag lines across the chest, indicating a need for more volume in the front shoulder area. She guides viewers through the process of adapting only the front pattern piece. Using tracing paper, she demonstrates the "slash and spread" method to add extra volume.

The tutorial involves drawing a slash line on the pattern, cutting along it, and pivoting the pattern to create an opening. Izzy shows how to insert paper to widen the pattern by a specific amount (2cm in this example), adding volume to the armhole. She then demonstrates how to redraw the armhole curve to blend smoothly with the existing shape.

Izzy recommends cutting out the adjusted pattern piece to transfer the new shoulder shape onto the original block, using a different color to distinguish the alterations. She stresses the importance of trial and error in determining the exact amount of added volume needed. The video concludes with encouragement to explore other fit alteration tutorials in the series for a comprehensive understanding of bodice block adjustments.
