I recently ordered a custom tailored set of shirt, trousers, and belt. Their site was bragging about their great AI technology, but sadly I didn't notice that red flag early enough.
The results were nothing short of disastrous. I sent in my measurements and they sent me a trouser with wrong measurements and a postcard that said that they adjusted my measurements with AI for a better fit. The belt they included was a completely different size than the trouser and I'm still waiting for the shirt to arrive. And now I'm fighting the usual uphill battle to talk to a human and get this mess fixed or get a refund.
The core of Stitchfix is personalization, as they say. But that means an individual solution for each individual customer, and not AI for memorizing generic trends in a huge dataset.
