Some autumn trousers or leggings are not divided into front and back.
But almost all brands of autumn trousers or leggings with higher comfort are divided into front and back.
The way to separate the front and back of long johns or leggings is:
1.
The front of the leggings is shorter than the back,
2.
The buttocks area will have some folds in the production process, because the buttocks need to occupy a larger area of ??fabric than the lower abdomen, which makes it easier for you to move and is more comfortable without exposing your waist.
3.
Trademarks, washing labels, and ingredient labels are usually sewn on the back of long johns or leggings.
4.
For other identification methods, please refer to the product sales instructions.
