Master Tailor Knowledge · Understanding Fit
Master Tailor Knowledge
Good fit is not only about size. It comes from understanding posture, balance, proportion, and how a garment hangs on the individual body.
Measurements Tell Us Size. Balance Tells Us Fit.
The Fundamentals
The Four Foundations of Fit
Every evaluation Jin Lee performs begins with these four ideas.
Posture
How the upper body stands affects front/back garment balance.
Shoulder Slope
Left and right shoulder slope affect how a jacket sits and hangs.
Body Balance
Chest, back, waist, and seat projection affect how the garment balances.
Proportion
The relationship between torso, legs, shoulders, and garment length affects visual balance.
A Closer Look
Shoulder Slope Changes How a Jacket Hangs
Left and right shoulders may differ from one another, and shoulder slope affects how a jacket's shoulder seam sits and balances across the upper body.
This is not simply a shoulder-width measurement — it's about the angle each shoulder carries, and how a jacket has to be built to sit correctly on it.
A Body-Balance Measurement
Forward Neck Depth Helps Explain Upper-Body Balance
Neck position can be more forward or more erect from one person to the next, and this affects collar balance and the way the upper part of a jacket sits.
Forward Neck Depth is not a neck circumference measurement — it is a body-depth, posture-balance measurement.
A Body-Balance Measurement
Waist Depth and Seat Prominence Affect Front-to-Back Balance
A flatter seat creates less depth. A fuller or more prominent seat creates more depth. Either way, this affects how trousers and the lower part of a jacket hang.
This is not a waist circumference measurement — it is a body-balance measurement, read in side view.
Beyond the Tape Measure
Why Measurements Alone Are Not Enough
Two clients may have the same chest, waist, and sleeve measurements but still need different patterns because their posture and body balance are different.
Same measurements. Different body balance. Different fit.
How Knowledge Becomes a Garment
Fit Knowledge Becomes Pattern Knowledge
Jin Lee applies personal pattern-making and technical fitting knowledge where it's needed — built on a simple sequence:
- Observe the Body
- Measure
- Evaluate Balance
- Adjust Pattern
- Fit
- Recheck
Is This You?
Who Benefits Most
This kind of evaluation matters most for:
- Difficult-to-fit clients
- Clients with uneven shoulders
- Clients with forward or erect posture
- Clients with a prominent or flat seat
- Athletic proportions
- Clients whose jackets pull, twist, or hang unevenly
- Clients who have not been satisfied by standard alterations
