attire

This term carries a strong connotation of formality and intentionality. It is rarely used for casual clothing like pajamas or gym wear, instead evoking images of ceremonial, professional, or high-fashion garments. The word suggests a curated appearance designed to signal status, role, or respect for a specific event.

As a noun, attire is an uncountable mass noun. It refers to the collective concept of clothing rather than individual garments. Therefore, one cannot refer to "three attires"; instead, phrases like "a piece of attire" or "items of attire" must be used to quantify specific articles of clothing.
