Shirts are made according to individual models for specific customers according to their specific size and style requirements. This is very different from the custom build, which is done by simply converting the bearing model or part of the bearing template to custom dimensions.
Whenever you order an original custom shirt, your own paper pattern is used to cut the fabric. Therefore, the result is the same for each order. If you order custom work, someone will translate your measurements and modify the existing model.
You can buy Custom Sublimation Shirts & Designer Sublimation T-Shirts at various online sources.
Customization almost always works well for customers with standard sizes and doesn't require unusual styles. Customers with fitness concerns or radically different style needs will do much better with a shirt made to size.
The adjustment process begins with the correct measurement—not just collar and sleeve length, but also chest, waist, armpits, lettering, and tail length—taking into account features that are difficult to measure, such as sunken chest area, shoulder slant, back rounding, etc.
The right fit is always important, but it's the design factor that so many customers are excited about. In my experience, it's about 70% for fit and 90% for styling. Even customers with fit issues will enjoy the variety of styles and fabrics available with customization.
