I am renowned for durability yet am not overly coarse.

I am the primary constituent in a garment worn after school.

I am integral to Westerns yet prefer to stay clear of spaghetti.

I am made with yield of cotton pickers yet better than suits who own them.

I am known to elicit joy yet am typically blue myself.

I am frequently used by labourers even though it was them who made me.

I am best with leather yet have developed a recent penchant for sneaking.

I am influenced by fashion yet to double up on me has long been a sin.

I am often used in conjunction with a fly yet can have a skinny style.

I am named in rhyme with serpent toxin yet am innocuous myself.

I am guilty of once being stone washed yet have since atoned.

WHAT AM I?
