Common Mistakes to Avoid

1. Inaccurate Measurements

Reason: Incorrectly measuring your bust, waist, and hip circumference can lead to a dress that's too tight, too loose, or ill-fitting in general.
Solution: Double-check your measurements and use a flexible measuring tape held snugly against your body.

2. Uneven Neckline or Shoulder Seams

Reason: Careless cutting or pinning can result in an uneven neckline or shoulder seams, ruining the overall aesthetic of the dress.
Solution: Carefully mark and cut your pattern pieces, and precisely pin them together before sewing.

3. Ignoring Fabric Grain

Reason: Cutting fabric on the bias or without considering the grain line will result in a dress that stretches unevenly and looks distorted.
Solution: Always ensure your fabric's grain line aligns with the pattern's markings before cutting.
