Takes a look at the upper classes (5)

I believe the answer is:

peers

I believe this is a double definition.

'takes a look' is the first definition.
(I've seen this in another clue)

'the upper classes' is the second definition.
(peer is a kind of upper class)

'at' acts as a link.

(Other definitions for peers that I've seen before include "Looks searchingly" , "Looks closely at equals" .)

I've seen this clue in the Sydney Morning Herald.
