The zigzag seam is mostly used in lingerie because it provides flexibility and stretchability, which is essential for comfortable and form-fitting undergarments.

A flat seam is a type of seam that lies flat against the fabric, without any visible bulk or raised edges. It is commonly used to join two pieces of fabric together while minimizing bulkiness. In this case, the question states that a flat seam is to be used to fix allowance on one side only. This means that the seam will be used to secure the fabric allowance on just one side, while leaving the other side untouched. Therefore, the correct answer is true, as a flat seam can indeed be used in this manner.

The bound seam is a suitable method for finishing the neckline and arm line of knitted fabrics.

The correct answer is "To avoid unfinished seam margins." French seams are used to enclose the raw edges of fabric within the seam itself, creating a clean and finished look on both sides of the fabric.

By using French seams, the seam margins are fully enclosed and there are no raw edges left exposed, resulting in a polished and refined appearance.
