Suitable thrifts in Dallas for 30s-50s clothing?

[MondoFW]

Members familiar with Dallas, TX, I need your help! With so many thrift stores here, it's very difficult to weed out the ones that are flooded with 20-year-old garbage. Since I'm vacationing here, I would love to be exposed to stores known for selling Golden Age clothing, if any.

Opinions on prices, service, and availability are also appreciated.
