Robert Best's "Silkstone" Barbie Fashion Model Collection is considered by many doll collectors to be the pinnacle of Barbie.  These dolls were inspired by the aesthetic of the vintage original and have been elevated with elegant fashion using high end textiles and immaculate attention to detail.  Their bodies are made of a dense, heavy weight vinyl that is intended to resemble the feel of porcelain.

This is the "Black Enchantment" outfit, released in 2001.
