Underwear straps often fall off. Why is this? Is there any way to solve it?

What should I do if the underwear shoulder strap keeps falling off? 1. Adjust the shoulder strap to an appropriate length. If the shoulder strap is loose, please adjust and tighten it in time. 2. When wearing underwear, the posture of shoulders should be correct. Don't always shrug your shoulders and buckle in. This will also cause the shoulder strap to slip. 3. Sticking double-sided tape on the shoulder strap can effectively prevent the shoulder strap from slipping. 4. Cross the underwear shoulder strap behind your back, or tie the back shoulder strap with a rope, which can effectively prevent slipping. The reason why the underwear shoulder strap fell off was 1. The reason why the shoulder strap fell off was that your underwear didn't fit. Maybe your underwear is too big, causing the shoulder strap to slip. If this is the case, you must change your underwear in time, otherwise it will cause your breasts to sag. Because the shoulder strap can support our chest, if it slips, the whole chest will lose its balance and sag. 2. Wearing underwear for a long time will also cause the shoulder strap to fall off. Wearing underwear for a long time will loosen the shoulder strap. When such underwear is worn on the body, the shoulder straps will not be elastic and the shoulders will fall off on their own. 3. Our shoulder structure will also cause the shoulder strap to slip. If you are slippery, it is difficult to put the shoulder strap on your shoulder smoothly. It will slide slowly on your arm, just like a slide. 4. Poor quality can also lead to shoulder straps falling off. Usually, the gear is of poor quality, and it will lose its elasticity after being worn several times. Usually, we have to go to a specialty store to buy underwear. The effect of the decline is also very good. Improper drying may shorten the life of underwear. Underwear is best washed by hand, and it is best to take it off the underwear belt. Don't hang the belt directly on the hanger to dry, so the whole bra will stretch the shoulder strap and make it lose its elasticity.
