[Mermaids] Wouldn't they smell really bad?

I mean, they're covered in shellfish and stuff like that. 

They look alright from afar but surely the closer you get the stronger the smell of fish would become.

Edit: I formally apologise to all the merfolk out there, I did not mean any offence. I was merely misinformed.

Fish only smell that way if they're sick or decomposing. A live or freshly dead fish smells fairly clean. 

As for their accessories, merfolk tend to use still-living creatures bred for use as garments or thoroughly clean the shells of dead ones.
