'garment manufacturers' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'designed kit with tennis legend' is the wordplay.
'designed' indicates an anagram (designed with the letters).
'with' says to put letters next to each other.
'tennis'+'legend'='tennislegend'
'kit' put after 'tennislegend' is 'tennislegendkit'.
'tennislegendkit' is an anagram of 'KNITTING-NEEDLES'.

Can you help me to learn more?

(Another definition for knitting needles that I've seen is " tools for craftspeople".)
