To hesitate to accept or do something out of, often affected, shyness or modesty.

Pay attention to the reflexive pronoun 'sich' (oneself). Without 'sich,' 'zieren' means to adorn. With 'sich,' 'sich zieren' means to hesitate out of shyness or for show.

When 'zieren' means 'schmücken' (to decorate/adorn), the decoration is the subject of the sentence, and the place or object being decorated is the accusative object. This structure is typical of an elevated register.

The command 'Zier dich nicht!' (Don't be coy!) is a very common colloquial expression. You say it to someone who hesitates to accept an offer, in order to encourage them.

to decorate
Both Schmücken and zieren can refer to making something more beautiful with decorations. Schmücken is the usual, broad verb for the active action. Zieren often sounds more literary and frequently describes a decoration that is already visibly attached to a place or object.
