My red robe I fashion with decorative design (10)
I believe the answer is:
embroidery
'decorative design' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'my red robe i fashion' is the wordplay.
'fashion' indicates anagramming the letters.
'my'+'red'+'robe'+'i'='myredrobei'
'myredrobei' is an anagram of 'EMBROIDERY'.
'with' is the link.
Can you help me to learn more?
(Other definitions for embroidery that I've seen before include "Creative sewing" , "Decorative needlework" , "The art of sewing patterns" .)
