Four Steps to Wear Your Arm Shaper (Long Sleeves)
Step 1
Initial Positioning
Slide both arms fully through the long sleeves. Position the garment so the U-shaped bra panel sits at the correct bust level and the front panel rests flat against the chest and upper abdomen. Pull the sleeves down smoothly from shoulder to wrist, ensuring even fabric distribution along the full arm.
Step 2
Clasp Fastening
Fasten the three-row front clasps from the bottom upward. Choose the clasp row that gives a firm, comfortable fit without restricting breathing. The front panel should lay flat with no gaps or bunching at the center.
Step 3
Back Adjustment
Check that the X-shaped back panel sits flat and smooth across the upper back and shoulder blades. The structure should gently pull the shoulders back without restricting arm movement. Smooth the sleeve from shoulder to wrist and adjust so there is no bunching at the underarm or elbow.
Step 4
Final Mirror Check
Stand in front of a mirror and check the front, sides, and back. The full arm should appear smooth and slim from shoulder to wrist, the bra line flat, and the shoulders visibly upright. The front clasps should sit secure with no gaps or pressure points.
