Yes, the department store, when it first appeared, was quite the revelation, and caused a great shift in patterns of shopping. I've read some scholarly works on that era in retail and marketing and it's fascinating. Emile Zola set a novel in a department store, too - I think it's called Au Bonheur des Dames (forgive me if I'm massacring the French).
I grew up in a rural area in Indiana and I remember with fondness our trips to Chicago during the Christmas season when I was a kid. We used to walk around and look at all the gorgeous holiday window displays Marshall Fields did for the season, and shop for all kinds of stuff that neither our poky town nor Indianapolis had in stores. With the rise of the Internet and social media, trends get dispersed around a lot more quickly. But online buying has made some rural areas without many B&M options for shopping other than Walmart and the dollar store.
My friend who is a happy Stitch-Fix-er has two kids under three and can only shop when they're asleep. She knows what she likes but she doesn't have much patience for browsing (never did, even before she had kids, but now she doesn't have the time at all). So I can see why she likes Stitch Fix - it's a fun surprise, it feels like an indulgence but it's not crazy expensive, and it's a good way to nudge yourself out of a comfort zone just a little.
