Help please, the last three clues are bugging me somewhat...
10 (Ac) - Attire, clothing (4) : G---
11 (Dn) - Showing no compassion (8) : --T---S-
17 (Ac) - Showy garden flower (6) : -A---A
I may well have 1 down incorrect, which I have as DISAGGREGATE (the clue being 'separate into component parts).
