What kind of underwear is a good underwear?
I think it should include the following aspects:
1. Tailoring & comfort. The most important thing, of course, is comfort.
2. Ventilation & moisture removal of fabric. No matter what season, good ventilation and sweat absorption are essential for little brothers.
3. Whether the workmanship is durable. Do not deform after washing, you can wear longer. (But also need to change the new time!)
4. Aesthetic degree. Although the underwear is worn inside, it must be good-looking.
5. Price. If you make a Positioning map, the price must be the abscissa.
