The established guideline regarding the wearing of light-colored trousers, particularly those of an ivory hue, traditionally links the commencement of their wear to the shift from spring into summer. This convention often aligns with Memorial Day in the United States, marking the unofficial start of the warmer season and a departure from darker, heavier clothing.
Adhering to this practice offers a symbolic transition, mirroring the change in weather and a general inclination towards lighter fabrics and brighter colors. It is further rooted in a historical context where practical concerns dictated clothing choices; lighter colors reflected sunlight, offering greater comfort in warmer climates. This sartorial shift can be seen as a way of embracing the anticipated shift in weather conditions and overall mood.
