Metail software may not be heard by many people. This software allows users to upload a photo of themselves and then submit their body shape information, such as height, weight, hip circumference, chest circumference and waist circumference. Relying on the technical services provided by Metail, a 3d avatar can be created to simulate consumers.

When consumers choose a pair of trousers, they can see which leg is high, where the hem is low, whether the belt height is appropriate, and even whether the fabric fits.
