The reason why the shoulder strap often falls off when wearing bra

1. The bra is worn for too long, causing fabric wear and natural slack in the shoulder strap.
2. After washing the new bra, hanging the shoulder strap directly on the hanger causes the weight of the cup to become heavier after absorbing water, and the thin shoulder strap falls down with the heavy cup, causing the elasticity of the shoulder strap to become loose due to damage.
3. The fabric itself has poor elasticity and is not durable.

4. The arc of the cup and the bottom edge of the breast do not match, resulting in a longer shoulder strap that slides off.If the depth of the cup does not meet the actual needs of the breast, the cup is larger than the breast and bounces upward, causing the shoulder strap to appear long and fall off.

5.Sometimes, we choose women bra with steel rims, but the size of the steel rims is also important. The size of the steel ring here refers to the arc size of the steel ring.
If the arc of this steel ring is too large, the outside of the steel ring will be closer to the outside, causing the contact area between the cup and the shoulder belt to be too large, resulting in shoulder slip. On the contrary, when the steel ring is too small, it will press against both sides of the breast or get stuck below the bottom edge of the breast, resulting in the inability to hold the entire breast when worn. The steel ring will start to slide upward, causing the shoulder strap to become longer and longer, and when the shoulder strap reaches a certain level, it will also slide off.
