1. First put the shoulder strap through your arm and let it fall on your shoulder naturally. Bend the upper body forward 45 degrees, let the breasts naturally and properly lean into the cup, and then buckle the back button.

2. Lift the breast completely by hand and put it into the cup, then gently press the bottom edge of the cup to fix the position of the bra, fully push the chest muscles into the cup and move the position of the cup, so that the chest lines are concentrated and the breasts are well contained, achieving the effect of smoothness and obedience.

3. Adjust the shoulder strap to an appropriate length, and the shoulder feels natural and comfortable without pressure. Remember that the shoulder straps should not be too tight or too loose.

4. Adjust the horizontal belt on the back to be flush with the bottom of the chest cup, and don't pull the horizontal belt on the back too high.
