Photorealistic virtual try-on means the result image looks believable enough that a shopper treats it as useful product information rather than as a novelty effect. That is the threshold that matters in fashion e-commerce.
Fashion purchases are unusually visual. The customer is buying identity, silhouette, proportion, and confidence. If the try-on image feels synthetic, distorted, or out of step with the product page, it fails the exact job it exists to do.
A useful merchant test is simple: would you be comfortable showing the try-on result to a customer who is about to spend real money on the product? If the answer is no, the tool is not product-page ready.
