Answer:
Silk
Step-by-step explanation:
Silk has been considered a luxury item since the 3rd millennium BC. However, it has always been considered a popular fabric. Silk is so prohibitively expensive due to the labor-intensive process of obtaining it. Silk is obtained from the cocoons of the larvae of the silkworm, which are usually raised in captivity. However, there are many modern textiles that are able to copy the appearance and qualities of silk.
