Instead of searching all Size 12 clothing for example you shop the size a certain model wears. Maybe 2 models per size bracket, so a person can match themselves to the models size and therefore if they have purchased something that fit them the same as the model, then it would add confidence to your ability to purchase an item in your correct size everytime. So for example if model "Emma" has these dimensions "....." And I also have those, then instead of searching in the drop down menu for size 12, I search Emma and it's all the sizes that would fit that model to help with size inconsistency between brands. Hopefully that made sense. 😂
