to choose very carefully from a number of possibilities; to be selective. You must take what you are given. You cannot pick and choose. Meg is so beautiful. She can pick and choose from a whole range of boyfriends.
Select with great care, as in John and Kate loved to go to the pastry shop, especially if they had time to pick and choose . Despite its redundancy ( pick and choose are synonyms), this phrase has survived since the 1400s.
