I would think Dallas would have some retailers who carry Bal - like NM and Saks. Do you have a Barney's - Barney's has a great selection of Balenciagas. It is always nice to see the bags IRL before you buy one, though many of us had our first experiences with Bal bags by buying them online and never seeing one IRL before our purchase.
There will be certain hardware/styles that will only be available in the Bal stores or Bal online.
Good luck, and welcome to our wonderful Bal world!
