Preparation and Safety Guidelines

Tools Needed
  • sewing machine
  • power mesh
  • outer fabric
  • lining fabric
  • 1-inch elastic
  • bra clasp
  • pins
  • scissors
  • iron
Safety Guidelines
  • Ensure your chosen tank top fabric has enough stretch and support for your bust. Using a flimsy fabric will result in an ineffective bra.
  • Accurate measurements are crucial. A poorly fitting bra can be uncomfortable and even harmful. Take your time and double-check your measurements before cutting.
  • Prioritize comfort and support. If the DIY bra feels uncomfortable or doesn't provide adequate support, do not wear it. A poorly made bra is better left un-worn than risked for health concerns.

Tips

  • Use a stretch stitch when sewing the bra to accommodate the stretch of the fabric.
  • Take care to ensure all three layers (mesh, lining, and outer fabric) are neatly enclosed during sewing.
  • Press all seams carefully for a professional finish.
  • Use a zigzag stitch to attach the elastic band securely and create a flat finish.

Common Mistakes to Avoid

1. Inaccurate Measurements

Reason: Incorrectly measuring your bust size can result in a bra that's too tight or too loose, compromising comfort and support.
Solution: Carefully measure your bust circumference and underbust circumference multiple times, following the pattern instructions precisely.

2. Ignoring Fabric Stretch

Reason: Using a non-stretchy fabric or failing to account for fabric stretch during construction will lead to a stiff, uncomfortable, and potentially ill-fitting bra.
Solution: Choose a stretchy knit fabric and account for the fabric's stretch properties by pre-washing and testing your chosen material.

3. Poor Seam Finishing

Reason: Leaving raw edges unfinished can cause fraying, discomfort, and a less professional look.
Solution: Use a serger, zigzag stitch, or binding to finish all seams to prevent fraying and improve the garment's durability and comfort.
