'jumper' is the definition.
(I've seen this before)

'oddly german's someone' is the wordplay.
'oddly' indicates alternate letters (letters in odd-numbered positions).
'someone' becomes 'shopper' (shopper is a kind of someone).
The alternating letters of 'germans' are 'gras'.
'gras'+'shopper'='GRASSHOPPER'

'buying a little green' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
