This may just be me, but keep in mind I got married a little older than the norm (37)...
I had a hard enough time finding a dress I loved, even in brick&mortar stores. I tried large discount places and small bridal boutiques all over the price spectrum. Eventually, I made some inquiries about local designers/seamstresses, and ended up having a dress made. I collaborated with a terrific artist who creates costumes for a theater company in my hometown.
I came to see that process as a full experience leading up to the wedding day. Even during the many frustrating moments of the search, and the scary moments of the design process (fitting the muslin, which does NOT look how the final garment will), I valued the interactions and relationships along the way. I sit at my computer every day and order all kinds of other stuff online, but I preferred the experience of shopping for something so significant in a more personal, interactive way.
Or maybe after years of self-employment working at home, I needed to get out more. Or I'm just old-fashioned.
