The reason why the bra shoulder strap keeps falling off:
1. Loose shoulder straps
Wearing a bra for too long results in fabric wear and natural relaxation of the shoulder straps.
2. The drying method is incorrect.
After washing the backless bra, hanging the shoulder strap directly on the hanger causes the cup to absorb water and become heavier. The thin shoulder strap falls off with the heavy cup, causing the elasticity of the shoulder strap to become loose.
3. The fabric itself has poor elasticity and is not durable.
4. Improper cup size
The chest shape is different, and the depth of the cup is also different. If the depth of the cup does not meet the actual needs of the breast, and the cup is larger than the breast, it will bounce up and slide, causing the shoulder strap to become longer and fall off. The curvature of the cup and the bottom edge of the breast does not match. The bottom edge of the cup is pressed against the breast root, and when wearing, the bottom edge of the breast cannot be retracted, causing it to bounce and slide upwards, resulting in the shoulder strap slipping off.
5. Improper steel ring
Sometimes, we choose seamless bras with steel rims, but little do we know that 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 curvature of this steel ring is too large, the outer side of the steel ring will be closer to the outer side, resulting in shoulder slip.
