1, pants version. The size of trousers on the waist is suitable, but it is easy to fall off when exercising, because there is something wrong with the style of trousers, so it is easy to fall off when walking.

2. The waistband is too big. I didn't re-measure the pants when I bought them, so they were too tight or too big.

I didn't wear it right. Whether the pants are too tight or too loose, if you wear them incorrectly, it will also lead to the problem of pants falling down.
