Just a bit flimsy with lovely tips (8)
I believe the answer is:
slightly
'just a bit' is the definition.
(thesaurus)
'flimsy with lovely tips' is the wordplay.
'flimsy' becomes 'slight' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'tips' suggests removing the centre (just the outer letters of the world).
'lovely' with its centre taken out is 'ly'.
'slight'+'ly'='SLIGHTLY'
(Other definitions for slightly that I've seen before include "Somewhat" , "a tiny bit" , "To a small extent" , "Quite!" , "To a small degree" .)
