What is the fastest way to get a wedding dress?

I'm curious, what's the quickest method for acquiring a wedding dress? Is it by visiting a bridal boutique and making a selection right away, or are there faster options available online, perhaps with expedited shipping? Additionally, could renting a dress be a viable option for those who need one in a hurry? I'm interested in hearing about any strategies or tips for securing a gown swiftly, as time may be a factor in my upcoming nuptials.
