A well-fitting suit does not mean the tightest possible suit. A good suit allows movement while looking clean when standing and sitting. The key is balance: shoulders, collar, waist and trousers work together.
The shoulders matter most
The jacket shoulder seam should end close to your natural shoulder line. If it drops down the arm, the jacket looks too large. If it sits too far in, the fabric pulls and movement feels restricted. Shoulders are difficult to alter later, so check them first.
The collar should not lift away from the neck
The jacket collar should follow the shirt collar without a clear gap. If there is space between the neck and the jacket, the issue may be posture, pattern shape or size. A good collar stays calm even when you move.

The button should close without pulling
When the top button is closed, the front should not create a strong X-shaped pull. A light waist shape is good, but the fabric should not strain. A jacket that is too loose loses structure.
Trousers should drape cleanly
With trousers, look at the waist, thigh, knee and length. The fabric should fall naturally without strong pulling around the pockets. Trouser length depends on style, but it should look intentional, not accidentally too long.
