The 'costume' of Ariel's that people are most familiar with.
There's not much to it, really! Purple shell bra, green fish tail, and a long red wig.

So how to make a shell bra?
One option is to take a strapless bra with a narrow strap around the back, and sculpt two shells to cover over the bust, hiding the Fashion Jewelry Store  cups.
Most clays should work for this, but something with a frame or armature would work well to help strengthen it. Just make sure if you do use air dry or water clay that you don't use an armature because the clay will try to shrink in around it as it tries and can crack.
My clay of choice is du-kit, it has a gentle flex, doesn't shrink or expand, and can be sanded or filed after being baked.

As for the tail, that'll be a bit harder, and it depends whether you're going for accuracy (and are stuck sitting) or want something you can walk around in.
For the fabric, go for a shimmery green fabric, or something that has a green 'fish scale' pattern on it. I personally don't like the look of sequins (far too shiny), It should have a stretch to it, in order to fit as snugly around your hips and legs as possible.
For the fins, use something lighter, and stiffer. If you're doing a 'walkable' costume, you may want fins that can be hooked up out of the way while walking, that can be let down for pictures.pearl necklace jewelry
