A friend wants to get into vintage in Sacramento– where do I send him?

[BigBrother]

Title pretty much sums it up , but a family friend, turns out, has always really been interested in 1940s automobiles, culture, music, and dress but really has only gotten so far into the automobile part. I started talking to him all about the swing dancing and vintage scenes and his eyes grew wide as saucers! He lives in Sacramento. I have no clue where to send him to find some sharp duds. Any advice? Thanks so much!
