According to the context of the book, I believe we could translate the sentence in this way:
"They painted, and decked
themselves out in gold and silver, even to walk to the grocery store. Or they went fresh scrubbed
and without ornament- it didn't matter."
"Eles (Elas) se pintaram e se adornaram em ouro e prata, até mesmo para caminhar até a mercearia. Ou eles (elas) foram limpos(as)
/ sem maquiagem / de cara limpa
e sem bijuteria - (isso) não importava."
: to cover = cobrir-se; disfarçar-se; vestir-se; adornar-se
(1): to clothe in a striking or elegant manner: to array decked out in furs
Related expression:to deck the halls with boughs of holly
— An English carol.
(3): to portray or present with embellishments.
= limpo; lustrado; sem maquiagem
- made clean by scrubbing / by force.
- A religious folk song or popular hymn, particularly one associated with Christmas.
