True fit is more of a conversion boosting tool rather than a tool to help the consumer.

I worked at Levi’s Corp for 3 years and was surprised to learn that clothes have large tolerances in sizes to keep costs down.

True fit says you should select a size based on the size you wear in another brand. That won’t work because no brands have consistent sizing. Even if a brand used extremely tight size tolerances, brands actively size up and down their clothes based on the whims of merchants.

The solution is to just buy 3 sizes of each item you want and select the best fit and return the rest.
