Linen; it is highly breathable and moisture-wicking, making it especially well suited to hot climates, while wool is chosen specifically for warmth and is not the appropriate choice when the priority is staying cool in heat and humidity.

Silk; it has a naturally smooth, lustrous surface with excellent drape, which directly supports the fluid, elegant silhouette and light-catching quality typically desired in eveningwear.

Not necessarily wrong in principle, but the specific execution may have been an issue; wool can feel scratchy without careful finishing, so the fiber itself might have been a reasonable choice for other properties (warmth, resilience), but a finer, more carefully finished wool (or a wool blend) might have addressed the scratchiness issue while retaining wool’s other beneficial properties.

Wool; it is described as resilient and wrinkle-resistant (springing back into shape well), while cotton is specifically noted as wrinkling easily – making wool the stronger choice when wrinkle resistance during travel is the priority.

Because silk is described as delicate, often requiring special care, and prone to easy water-staining; these qualities make it less practical for everyday, hard-wearing use where durability and easy care matter more than the elegant drape and luster that make silk so well suited to more delicate, occasion-based garments like eveningwear.

Linen; it is described as moisture-wicking even more so than cotton in some respects, meaning it may handle moisture (like sweat) somewhat more effectively than cotton, even though neither is necessarily the industry-standard choice for high-performance activewear (which often uses synthetic or blended fibers, covered in the next lesson).

Linen; it has a naturally crisp, textured hand (rather than a smooth one), which directly matches the brief’s specific requirement, in addition to also suiting the “summer” context through its strong breathability.

Because wool’s resilience (its ability to hold shape and resist wrinkling) is particularly valuable for tailored garments that need to maintain a crisp, structured silhouette over repeated wear, while cotton’s tendency to wrinkle easily would work against the clean, structured look a tailored blazer typically requires.

This assumption is incorrect because natural fibers vary significantly in their individual properties; for example, silk has a smooth, lustrous, delicate quality suited to eveningwear, while linen has a crisp, textured, highly breathable quality suited to hot-climate everyday wear – despite both being natural fibers, their performance, hand, and appropriate uses are genuinely quite different from each other.

Cotton; while both fibers have their own considerations, silk’s requirement for special care and its tendency to water-stain easily make it less practical for an average consumer’s frequent, no-special-routine laundering compared to cotton’s relative durability and more straightforward care.

Wool; it is specifically noted as moisture-wicking even when damp, making it a strong choice for outerwear that needs to remain functional and comfortable in unpredictable, potentially damp weather conditions, unlike fibers that lose their functional properties significantly once wet.

Silk offers an exceptionally smooth, lustrous surface and excellent drape – qualities that make it visually and tactilely appealing – but this comes at the cost of durability and ease of care, since it is delicate, often requires special handling, and stains easily with water; a designer choosing silk for frequent, everyday wear would be trading long-term practicality and low-maintenance durability for silk’s distinctive aesthetic and drape qualities.
