Well, That's a bit ... ummmm....

 

Broadly speaking, it's    errr..... some cloth?

Obviously, I'm playing to the crowd, and recognise this Child’s tunic with tapestry ornamentations, 4th- 6th century from the classic publication (Page 11) "Coptic Textiles in Tension of the Political, Economic and Cultural Developments of Egypt, Rome and Iran

Roya Deyjou, Mostafa Dehpahlavan, Kamal-aldin Niknami. "

Plus, I think this tunic is part of the Victoria and Albert Museum collection.

Bonus -
