How to measure your shirt

Place your best-fitting shirt flat on a surface and measure carefully. This gives a more accurate size comparison than body measurement alone.

Chest Measure across the chest Measure from one underarm seam to the other, then double the number for full chest measurement.
Shoulder Measure shoulder width Measure from one shoulder seam to the other across the back of the shirt.
Length Measure shirt length Measure from the highest shoulder point near the collar down to the bottom hem.
Sleeve Measure sleeve length Measure from the shoulder seam to the end of the cuff for full sleeve length.

Fit recommendation

GKSEN shirts are designed for a clean everyday look. Your ideal size depends on your body shape, comfort preference, and how you like your shirts to fit.

Regular Choose your usual size If you like a clean regular fit, choose the size you normally wear in shirts.
Relaxed Size up for comfort If you prefer extra room around the chest, stomach, or shoulders, choose one size larger.
Between Sizes Go with the larger size If your measurement falls between two sizes, we recommend choosing the larger size.
Check Compare before ordering Compare the chart with your existing shirt to reduce chances of size mismatch.
