Inside, outside, almost perfect (5)

I believe the answer is:

ideal

'perfect' is the definition.
(similar in meaning)

'inside outside almost' is the wordplay.
'inside' indicates a hidden word.
'IDEAL' is hidden in the letters of 'outside almost'.

(Other definitions for ideal that I've seen before include "Coal-mining waste" , "Embodying perfection" , "Textbook" , "Utopian; yardstick" , "Quite perfect, can't be improved on" .)

I've seen this clue in The Telegraph.
