How to Create a Blazer Pattern- Step-by-Step Guide to Drafting the Perfect Suit Jacket

How to Draft a Blazer Pattern

Drafting a blazer pattern can be a challenging yet rewarding task for any fashion enthusiast or beginner pattern drafter. A well-fitted blazer is a staple in every wardrobe, and creating your own pattern ensures a perfect fit and the ability to customize it to your preferences. In this article, we will guide you through the process of drafting a blazer pattern, from gathering the necessary materials to completing the final pattern.

1. Gather Your Materials

Before you start drafting your blazer pattern, gather the following materials:

– A ruler or measuring tape
– Pattern paper or tracing paper
– A pencil or pen
– A straightedge
– A French curve
– A protractor

2. Take Measurements

To create a custom blazer pattern, you need to take precise measurements of the person for whom the blazer is intended. Measure the following dimensions:

– Chest circumference
– Waist circumference
– Hip circumference
– Shoulder width
– Sleeve length
– Center back length
– Armhole depth

3. Determine the Pattern Size

Once you have all the necessary measurements, determine the pattern size by referring to a size chart. This chart will help you choose the appropriate size based on the person’s measurements.

4. Draft the Basic Block

The basic block is the foundation of your blazer pattern. Start by drafting the following blocks:

– The bodice block: Draw a straight line for the center front, center back, and side seams. Add darts for shaping.
– The sleeve block: Draw a straight line for the sleeve cap, sleeve hem, and side seam. Add a curve for the armhole.
– The collar block: Draw a triangle for the collar, with the base being the collar width and the height being the collar depth.

5. Adjust the Blocks

Adjust the basic blocks according to the person’s measurements. This may involve adding or subtracting width, length, or shaping. Pay close attention to the following areas:

– Chest: Adjust the width of the bodice block to fit the chest circumference.
– Waist: Add or subtract width from the side seams to achieve the desired waist circumference.
– Hip: Adjust the hip width of the bodice block to fit the hip circumference.
– Shoulder: If necessary, adjust the shoulder width of the bodice and sleeve blocks to match the person’s shoulder measurement.

6. Add the Blazer Details

Once the basic blocks are adjusted, add the following details to create the blazer pattern:

– Collar: Attach the collar block to the bodice block, ensuring it aligns with the shoulder seam.
– Lapels: Draw the lapel shape on the front and back of the bodice block, making sure they are symmetrical.
– Pockets: Add pocket flaps and pocket bags to the front of the bodice block, if desired.

7. Finalize the Pattern

Review the draft to ensure all measurements are accurate and the pattern is symmetrical. Make any necessary adjustments, and then transfer the pattern to your pattern paper or tracing paper. Once the pattern is complete, you can use it to cut out your fabric and sew your custom blazer.

By following these steps, you can successfully draft a blazer pattern that fits perfectly and reflects your personal style. Happy drafting!
