The original "confusopoly" link talked almost exclusively about pricing, and for good reason: pricing is based on numbers, which humans are bad at but computers are very good at, and every product in the catalog has a price, so it's easy to take the same tactic and apply it to all of the products.

I'm not sure trying to confuse people about whether a shirt has stripes on it would make as much sense. The purchaser seems likely to give up on picking an ideal shirt and just go with the cheapest result.
