Key Standards for the Jacket
Shoulder Line: The end of the shoulder seam aligns perfectly with the shoulder bone; the fabric does not shift haphazardly when raising the arm, and the edge of the shoulder pad lies flat and smooth against the shoulder.
Sleeve Length: With arms hanging naturally, the jacket sleeve reveals 1–2 cm of the shirt cuff underneath, ending right at the wrist bone.
Chest and Waist: When the main button is fastened, there is enough room in the chest to comfortably fit a fist without causing tight, diagonal creases; the waist fits snugly without creating horizontal folds.
Jacket Length: The hem covers two-thirds of the buttocks; with arms hanging naturally, the hem falls somewhere between the thumb knuckle and the web of the thumb.
Key Standards for Trousers
For formal occasions, the trouser hem creates a single slight break (crease) on the shoe; casual styles may be cropped to ankle length. The seat and crotch area fit comfortably without tightness or excess, loose fabric.
