Couple problems, clothes are not food, you don't new ones everyday.

The other is apparel just has too much competition. Each retailer used to have a look and style they were promoting. There was also noticeable difference between low cost clothes and higher ones. If one goes to a mall the differentiation between stores is less than it used to be. I don't have a way to quantify this but that is what it seems.

As for cost of garments, go to H&M and go to Nordstrom, is there a quality difference, yes but not that much.

Back to stichfix, once customer has a few boxes of clothes and the customer likes the clothes, they can go buy them and a ton of other places. And unlike trying to replicate meal kit companies offerings, there is no preparing of a meal, just clicking the buy button.

Hard business.
