That was a startup two decades back. Built on automated pattern cutting. MVP was customized khakis. You'd enter detailed measurements on a website; machine-cut parts were assembled "manually" the next-ish day; then FedEx. Had a little tag with a number, so you could order "just like N, but let out a 1/2 inch". It was nifty.
It was acquired by Levis, which mismanaged it into nonexistence. Last-ish factory in the US providing that assembly closed, plus the patent, and that was the end of that. IIRC.
Perhaps in China? Years back, if you needed a new wardrobe of suits, it was worth a trip to HK just for that.
Modern Tailor offers MtM clothing starting at like $50.
Perhaps this was a niche in which US apparel manufacturing might have remained viable, with customization and shipping proximity supporting the extra US costs. It seems regrettable that the possibility wasn't better explored.
Coincidentally, this is likely the highest margin department in the store.
I’ve never in my life felt going to a department store I’d be met by someone knowledgeable in an area other than makeup.
One thing I’d have loved to see - an emphasis on customization and tailoring. Almost everyone could use a little custom tailoring for pants, blouses and shirts, and it does not scale online well at all as you need to be in person to get measured. If you like a shirt and it’s ill fitting, pay $15/20 for a cheap hem job and walk out feeling like a million bucks.
