What fabric is described as a fine soft sheer material commonly used for blouses or baby clothes?

The choice of batiste as the correct answer highlights its characteristics as a fine, soft, and sheer fabric. Batiste is typically made from cotton or a cotton blend, which gives it a lightweight and delicate quality, making it an ideal option for garments such as blouses and baby clothes. The soft texture is gentle against the skin, contributing to comfort, particularly in clothing designed for infants.

In contrast, buckram is a stiffer fabric often used for inflexible purposes, such as bookbinding or interfacing in garments. Twill is a weave pattern that produces a diagonal rib, resulting in a more durable fabric commonly seen in items like denim or workwear, rather than in soft, sheer garments. Canvas is a heavier, plain-woven fabric, typically used for items like tents, backpacks, or shoes, which also does not align with the requirements of a sheer material for clothing. Therefore, batiste stands out as the most suitable choice for the description given.
