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.

Shoulder Slope Left and right shoulder balance can change how a jacket hangs.

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.

Waist Depth / Seat Prominence Waist depth is a Master Tailor body-balance reference — not a circumference measurement.

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:

  1. Observe the Body
  2. Measure
  3. Evaluate Balance
  4. Adjust Pattern
  5. Fit
  6. 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
