long velvet dress

Velvet is a type of woven tufted fabric in which the cut threads are evenly distributed, with a short, dense pile, giving it a distinctive soft feel. By extension, the word velvety means "smooth like velvet". In the past, velvet was typically made from silk. Today, velvet can be made from linen, cotton, wool and synthetic fabric.

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystal are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.
