How to make a mermaid tail from a piece of cloth

Generally silicone materials, man-made fibers, polycarbonate materials, glass fiber, synthetic elastic fibers, neoprene, etc. Different products have different prices, the materials and quality used will also be different, and the appearance, elasticity, wearing comfort and mobility of the finished product may also be different.

Attached is the relevant content about the production of foreign mermaid tails, for reference only:

In 2005, Lyndon Wolbet, a woman from Los Angeles, California, became a Hollywood special effects actor. With the help of Len Holt, he built a fish tail based on his own body shape based on a fiberglass mold. In order to achieve a realistic effect, thousands of fish scales were specially carved out and then filled with high-quality silicone to make the fish tail more realistic. The tail can swing freely in the water. The entire process took seven months and cost ￡10,000 (approximately $16,000). Volbert's "tail" is about 1.83 meters long and weighs nearly 16 kilograms. As a professional diver and underwater photography model, she can hold her breath and swim underwater for 5 minutes at a time, reaching a maximum depth of 35 meters underwater. She can swim at a speed of about 27 kilometers per hour using her "tail".

Ms. Nadia Vichy, who was born in Auckland, New Zealand, has lost her legs since she was a child, but she has always been fond of swimming, so Vichy contacted Yin Prop Production with the mentality of giving it a try. The talented Weta Film Production Studio, renowned in New Zealand, asked if they would help them make a mermaid tail for swimming. What she didn't expect was that Weta's staff readily agreed. The Weta design team used 3D simulation and pressing hybrid technology combined with vacuum forming technology to create the mermaid tail. The spine and tail fin of the fish's tail are made of polycarbonate. The inner part of the tail skin is a layer of neoprene, and the outer layer is synthetic stretch fiber digitally printed with a beautiful fish scale pattern, which was specially designed by a concept designer. The unique fish tail finally allows Vichy to swim freely in the water like a mermaid.
