People choose to wear their clothing in different ways. Some like their jeans loose and baggy. Some like them precisely fitted. Some like them tight. Some like them VERY TIGHT. Its fine and good that people wear their clothes differently, even the same item differently.
If a clothing manufacturer lists their sizing based on body measurements, the result is that they must base them on one particular fit. Customers will inevitably complain that the item is tighter or looser than they desire because they are looking for a different fit. And it gets complex fast with numerous measurements of different parts of the body. Suits are traditionally sized in this way. It works for suits because they are typically custom tailored, dry cleaned, not subject to shrinkage, and tend to have a particular intended fit.
The other way is that a manufacturer can list their sizing based on actual measurements of the clothing. In this approach customers can best determine their size by measuring a piece of clothing that has a fit they wish to duplicate. This is how Gustin does it. I think its the right approach for them given the type of clothes and their business model. This approach also allows easy measurement of the items pre-wash and pre-wear to confirm they are within spec prior to shipment by the manufacturer and after receipt by the customer.
I measure all my Gustin items before I wear or wash them to see if they are within a reasonable +/- 0.5" tolerance. I have 20 or more items and 100% of them have been close to spec.
It wouldn't make any sense for a manufacturer like Gustin to try to pre-adjust sizing for shrinkage since shrinkage varies greatly based on fabric, how tight the item fits the customer, how the item is washed and dried, etc. And Gustin items are often sold at particular sizes with new fabrics that have never been used before, so how could anyone accurately predict the shrinkage and post-wear/wash/dry sizing? Its best for Gustin not to pretend they are psychic and instead make, measure, and mark their clothes at a new unwashed state.
I think Gustin has done it exactly right to clearly publish their sizing guide for all items including detailed dimensions, instructions for how to measure clothes with the fit you want to reproduce, and marking items based on clothes size instead of body size and when new not extrapolated after wear/wash/dry.
That being said, Gustin should be making quality control measurements on every single item prior to shipping so there should be zero stories of items arriving at a customer way out of spec. There are such stories and no valid excuses for that. But I do think its been fairly rare over the last 6-12 months based on my personal experience with numerous items.
