Get brown belt (3)

I believe the answer is:

tan

This clue is a double definition.

'get brown' is the first definition.

'belt' is the second definition.
(I've seen this before)

(Other definitions for tan that I've seen before include "Acquire a sunburn" , "Make black and blue" , "Yellowish brown" , "Shade of brown" , "Lie in sun" .)

I've seen this clue in The Times.
