Sept 2025
We’ve Updated Our Men’s Size Chart 

As of 1st September 2025, The Jacket Maker is introducing a new men’s size chart designed to help you find your perfect fit with confidence.

We heard your consistent feedback that our sizes tended to run small, and this update is built directly on what you shared with us. 

Our goal was to make shopping smoother by reducing sizing doubts and returns, while also catering to a much broader spectrum of sizes within our inclusive regular size range.

After extensive research, rigorous quality checks, and public testing, we finalized this chart to provide more accurate sizing across all styles so that you can shop with greater ease and certainty.
