Seam allowances are typically narrower for which of the following purposes?

Seam allowances are typically narrower when sewing delicate fabrics to minimize the bulk and ensure a smoother finish. Delicate fabrics, such as silk or lightweight chiffon, can be more challenging to work with due to their fine texture and tendency to fray. Using a narrower seam allowance helps to reduce the overall thickness of the seams, allowing the garment to drape more softly and enhancing its overall aesthetic.

In contrast, wider seam allowances might create unnecessary bulk, compromising the delicate look of the fabric and potentially leading to a less polished final product. This consideration is crucial in garment construction, particularly for items where a clean and elegant appearance is needed. Additionally, this approach helps in handling and manipulating the fabric without causing damage or shifting, which is particularly important with fragile textiles.
