Bridal dress SOS

Having a bit of a wedding emergency. My fiancé and I dropped off her wedding dress to a local tailor back in January. She lost about 70 pounds since she bought the dress, so she needed a lot of work done on it, which is why we dropped it off so early. We had trouble reaching the tailor, and find out yesterday not only is the dress not done, it hasn't even been started. There are now holes where the pins were left for so long hanging, and somehow stains on it too. Our wedding is next Saturday, 4/20. We got our money back and now only have this Saturday to actually search for an off the rack dress. No other tailors in our area could fix it in time with the amount of work it needed, and with it being prom season (or without charging us as much as we paid for the damn dress.)

We're trying some local shops here first, but if we can't find anything this Saturday, we're going to Houston Sunday. Any recommendations for bridal stores in the Houston area? We are trying to keep it under 2k. We are just at a loss at this point. I realize most are appointment only.

TLDR; Tailor fucked up, we have no dress, and wedding is in a week. Need shop recs in Houston for under 2k.
