deck

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

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

I don't understand the remainder of the clue.

(Other definitions for deck that I've seen before include "Adorn; pack of cards" , "Pack - embellish - ship's floor" , "Pack - floor in boat" , "Pack - part of record player" , "Set of cards" .)

I've seen this clue in The Globe and Mail.
