The core method of distinguishing pantyhose: the front is usually one stitching line and the back is two stitching lines.
This is a direct judgment method based on the number of stitching lines and design features, which can be distinguished more accurately in combination with other auxiliary methods.

Specific distinguishing method
Number of stitching lines
One line in the front, two lines in the back: This is the most common way to distinguish. The front design is simple, with only one stitching line; the back needs to cover a wider area of the buttocks, so two stitching lines are often used to increase the wrapping.
Trademark location
Most pantyhose will sew the trademark at the waistline on the back, so the side with the trademark is usually the back.
Elasticity test
The elasticity of the front is usually stronger to adapt to the bending of the leg. The difference can be felt by stretching comparison.
Design details
Some styles will be designed with a more leg-friendly cut on the front (such as reinforcement at the knees or ankles), and the back may be looser.
Special cases
If there are two lines on both the front and back, it may be a style designed for special body types, which can be distinguished by the marks on the knees and heels after wearing.
Some pantyhose without heels need to be judged in combination with other methods.
The distinction of pantyhose can also be further confirmed by combining the trademark position or elasticity test.
