Groom’s shirt in black satin with ruffles

• Posture:

Stand upright and relaxed—do not puff out your chest or suck in your stomach.

• Chest circumference:

Measure under the armpits without pulling the tape too tight. Leave room for one finger of ease.

• Stomach circumference:

Measure at the widest part of your abdomen (above the navel), without extra ease—just the exact measurement.

• Waist circumference:

Measure just above the hip bones, at navel level. Gently engage your stomach for a snug, body-hugging fit without ease.

• Hip circumference:

Measure around the fullest part of your seat, without pulling tight—leave room for one finger of ease.

• Trouser length:

Measure from the hip bone (with trousers properly positioned) down to your desired length, including the waistband.

• Sleeve length:

Measure from the top of the shoulder seam (armhole crown) to your desired sleeve length.

• Neck circumference:

Measure diagonally, mimicking the collar of a dress shirt. Never measure horizontally—it will give an incorrect size. Always leave room for one finger of ease.
