When starting a fashion business, one of the key aspects you'll need to understand is the importance of patternmaking, specifically the creation of the first pattern in the base size. In this blog, we’ll break down why patternmakers focus on the base size to begin the process, how patterns are graded to create additional sizes, and the role of 3D technology in ensuring the accuracy of your designs.
This guide is designed to help fashion entrepreneurs like you understand the crucial steps in patternmaking, grading, and how modern tools such as Clo3D can save time and money while ensuring quality across all sizes. Let’s dive in!
What is a Base Size?
A base size is the foundational size in which a garment's first pattern is created. Typically, the base size is chosen based on the target market's average size or the designer's preference. For example, a women’s clothing line may use a size 8 or 10 as the base, while a men's line might start with a medium.
The reason patternmakers focus on the base size is that it sets the proportions, style, and construction of the garment. From this base, the pattern is then "graded" to create the additional sizes needed for a full size range (e.g., XS, S, M, L, XL). If the base pattern is well-constructed, it ensures a smoother and more accurate grading process, which in turn leads to better-fitting garments across all sizes.
How Patterns Get Graded to Create Additional Sizes
Grading refers to the process of proportionally increasing or decreasing the size of a pattern to fit a range of body sizes. After the base size is established, the pattern is graded up (to larger sizes) or down (to smaller sizes) by adding or subtracting increments across specific points of the pattern.
Grading is not a one-size-fits-all process; it requires expertise to ensure the garment retains its design integrity and fit across the entire size range. The increments, pr grade rules, used in grading depend on the size steps and the type of garment, whether it's fitted, or oversized. For instance, a compression garment will have different grading rules compared to a loose-fit jacket.
Key Points to Consider During Grading:
Proportional changes: Grading involves adding or reducing width and length in key areas like the bust, waist, hips, and sleeve length.
Maintaining design elements: Features like darts, tucks, gathers and pleats need to be adjusted carefully to avoid distorting the overall look and maintain proper fit and proportion.
Grading rules: Experienced patternmakers apply specific rules to different parts of the garment to ensure consistency and proper fit.
How Distortion Occurs in Grading (Especially With a Wide Size Range)
As the size range increases, one of the main challenges is maintaining the garment’s original proportions and style. When a pattern is graded too far from the base size, distortion can occur. For example, a grade rule may dictate a certain amount of moment necessary for a grade point on one style, but if that grade point is in a slightly different location on a different style, it can throw off the entire look on the bookends of the size range.
Here’s how distortion can creep in:
Proportional misalignment: Grading changes the dimensions of a garment, but if the increments are too small or too large, the fit may be compromised.
Fit issues: Areas such as the neckline or armholes may lose the correct 90-degree angles at the corners causing an awkward look and causing difficulty with sewing.
Style integrity loss: If not properly managed, grading can warp design details, changing the original vision of the garment.
How 3D Samples Help Ensure Proper Grading Across Sizes
This is where technology steps in to save the day! Using 3D samples in software like Clo3D allows patternmakers to visually check the graded patterns across all sizes. With 3D technology, we can simulate how a garment will look and fit on various body sizes before any fabric is cut. This process helps to catch potential distortions early on, ensuring that the design remains true across every size.
Benefits of Using 3D Samples in Grading:
Visual feedback: You can see how the garment looks in every size, making it easier to spot inconsistencies.
Accuracy: 3D simulations allow for precise measurements and adjustments to be made in real time.
Cost-effectiveness: By identifying fit issues in the digital realm, you can avoid the cost and time involved in producing physical samples that might need alterations.
In my 8 years of experience specializing in pattern grading and utilizing 3D samples, I’ve seen firsthand how this technology reduces errors and ensures a cohesive look across all sizes. For fashion entrepreneurs, it’s a game-changer.
Collaborating With Freelancers for 3D Sample Review and Fit Testing
For designers or fashion startups, working with a freelance patternmaker offers flexibility and access to expert services. As a freelance patternmaker with extensive experience in Clo3D, I can help you by taking the dimensions provided in your tech pack and inputting them into the 3D software to create virtual samples.
Here’s how the process works:
Tech pack review: I’ll carefully review the dimensions and specifications from your tech pack to ensure everything is clear and accurate.
Pattern creation: Based on your measurements, I’ll develop the base pattern and simulate the garment using Clo3D to see how it fits.
Grading and 3D review: I’ll grade the pattern and simulate the various sizes to check for distortion and ensure the design holds up across all sizes.
Feedback: I’ll provide you with visual feedback and recommendations, allowing you to make informed decisions before moving to physical production.
This level of collaboration ensures you have highly accurate product specifications while keeping costs low and maintaining a smooth workflow.
Benefits of Testing Patterns in 3D
Testing your patterns in 3D offers a wide range of benefits, especially for new fashion entrepreneurs. It’s an innovative approach that bridges the gap between creative vision and technical execution.
Top Benefits:
Reduce Costs: By working with 3D samples, you can avoid costly physical prototypes and unnecessary fabric waste.
Faster Turnaround: Digital simulations drastically reduce the time needed to test fit and make adjustments.
Improved Communication: 3D samples can be shared with manufacturers and teams around the world, offering a clear visual representation of the final product. Factories are better able to understand your vision and desired look with the help of 3D prototyping.
Sustainability: The reduced need for physical samples means less waste, contributing to a more eco-friendly fashion process.
The Accuracy of Digital Patternmaking in Clo3D
Clo3D is one of the leading tools in digital patternmaking, offering unparalleled accuracy in creating virtual garments.
