Let's do some good old PoE.
It's not Tie, because really, you would have given the clue Shoe for Sock/Tie.
It's not Tale, because Santa Claus would be a clue for Sock/Tale, and I see no convincing connecting to Vargas.
Is it Paste? I don't see how paste has anything to do with the clue. So I guess not.
It could be Aztec, if Vargas has some sort of Aztec ancestry, but I don't know about that and it doesn't feel right to google.
Face... well I guess people have faces, so there. However, it could just as well be the red word. Possibilities for that one run out too. Sock/Face also seems like a clueable combination.
Watch... well, you watch sports, that could be valid. You also watch concerts, so ugh, it could be red for the same reason.
Finally, Mint. Well, smell kinda works for sock/mint, no?
It seems like the possible words are also possible for red, which is ugh. However, Aztec seems like a stretch, so I'm going for
Watch.
