Pete gets round it being small (6)
I believe the answer is:
petite
'small' is the definition.
(similar in meaning)
'pete gets round it' is the wordplay.
'gets' indicates putting letters inside (gets can mean captures or absorbs).
'round' is an anagram indicator.
'it' is an anagram of 'ti'.
'pete' going around 'ti' is 'PETITE'.
'being' acts as a link.
(Other definitions for petite that I've seen before include "Wee" , "Short" , "Little French" , "Small and attractive" , "Attractively small" .)
