Some weaknesses of denim fabric include:
Stiffness: Denim can be initially rigid and may require breaking in to become more comfortable.
Lack of breathability: Denim is not as breathable as other fabrics, which can make it less suitable for hot and humid weather.
Fading: Denim tends to fade over time, especially with frequent washing, which can alter the appearance of the garment.
Heavyweight: Denim fabric is generally heavier compared to lighter fabrics, which may affect comfort, particularly in warmer climates.
