Maybe. But I can see the appeal in many other eras and styles that I didn't grow up with and have no business relating to...
Is it "insecure" to want a garment that fits the human form and doesn't bunch / ride up / fall off my shoulders / let in the breeze? This doesn't even have to do with fashion from an aesthetic perspective, it has to do with function and comfort. (Lord knows, I gave up on "glam" fifteen years ago...)
It took me years, but I finally started to appreciate high-waisted jeans after it dawned on me...oh, you can tuck IN the shirt. (I also have wide hips, but most importantly a nickel sensitivity. So getting this layer of fabric between my belly and the top button was a game changer! And allowed for more comfortable sitting haha.)
It's interesting that you mention sewing. I'm not very crafty, but maybe I could find a tailor/seamstress to make the simple kind of summer dress that I find flattering & comfy: a knee-length cylinder of fabric, somewhat form-fitting but not bandage/bodycon-level slinky, with basic straps rather than boho pouf sleeves or fringe or whimsical off-the-shoulder cuts.
P.S. I was also kind of a goth in HS, but less baggy goth and more Shirley Manson/Faith the Vampire Slayer inspired, with a bit of skapunk influence from my peer group. But I'm too lazy to accessorize these days ;) So at home it's 90% athleisure, and in the office it's the traditional business (casual) wardrobe I established ~10 years ago. Only, that's starting to feel too formal, and I'm trying to reclaim an actual sense of style.
