Second Fiddle

I am always the sidekick

Never the main attraction

I am always the sidekick

But give you satisfaction

Accepted as is by the minority

As most feel the need to dress me

I can be topped in red, white, or clear

Either straight or curly is how I appear

Very popular in places that are fast

Enjoyed so much that not long do I last

What am I?
