Those dressed up figures (5)

I believe the answer is:

nines

I'm a little stuck... Click here to teach me more about this clue!

'figures' is the definition.

I don't understand the rest of the clue.

(Other definitions for nines that I've seen before include "Dressed to these is to be perfectly turned out" , "squares" , "9s" , "Numbers to which one may be dressed up?" , "In emergency, press three of these" .)

I've seen this clue in the Evening Standard.
