Onepiece dress 2 Sewing Patterns | DRCOS Patterns & How To Make

This is a free sewing pattern and tutorial for a fitted dress with shaping darts at the shoulder and armhole, designed to create a more defined silhouette. The base size has a relaxed fit, making it comfortable for everyday wear, handmade fashion, or stage and cosplay costumes. For a closer, body-hugging fit—especially for cosplay—it is recommended to select one size smaller or adjust the pattern lines to match your measurements.

The shoulder and armhole darts help the dress contour to the upper body while keeping the waistline smooth and flattering. You can also modify the neckline, sleeve length, or hem shape to customize your design. This pattern is versatile and suitable for both formal and casual looks, depending on fabric choice and styling.

The pattern includes a built-in seam allowance (S/A) for convenience. After printing, simply align the joining lines on the sheets, cut along the outlines, and you can start sewing immediately. Ideal for intermediate beginners looking to practice dart sewing, as well as experienced sewists seeking a reliable base pattern for dressmaking.

The production process is explained with translation software.
