Impressive carriage in attendance (8)
I believe the answer is:
presence
I believe this is a double definition.
'impressive carriage' is the first definition.
(carrying oneself with presence or importance)
'in attendance' is the second definition.
(I've seen this before)
(Other definitions for presence that I've seen before include "Demeanour" , "... of mind, the ability to remain calm and act quickly" , "Immediate proximity" , "Impressive carriage" , "Physical attendance or imposing bearing" .)
