Flower shape, people inspired by little one (6-2-3)
I believe the answer is:
forget-me-not
'flower' is the definition.
(I've seen this before)
'shape people inspired by little one' is the wordplay.
'shape' becomes 'forge' (synonyms).
'people' becomes 'men' (men are people).
'inspired by' means one lot of letters goes inside another (some letters breathed in or 'inspired' by others).
'little one' becomes 'tot' (I've seen this in another clue).
'men' placed within 'tot' is 'tmenot'.
'forge'+'tmenot'='FORGET-ME-NOT'
(Other definitions for forget-me-not that I've seen before include "Wild flower" , "Plant with small blue flowers" , "Small blue flower" , "Flower of remembrance" , "Myosotis" .)
