How to measure — Football Shirt
A
Chest / Width
Around the fullest part of your chest, under the armpits. Keep tape horizontal.
B
Shirt Length
From the top of your shoulder (at neck) straight down to where the shirt ends.
C

💡
The shirt width in the chart = half the chest circumference. Multiply shirt width × 2, then subtract your chest measurement — aim for 4–6 cm extra for a comfortable athletic fit.
ℹ️
Measurements in inches — garment measurements (the shirt, not your body). Classic boxy unisex fit. Women typically size down 1 from their usual size for a more fitted look.

How to measure — Cotton Tee
W
Width
Measure around the fullest part of your chest. Divide by 2 — this should be 1–2″ less than the shirt width.
L
Length
From top of shoulder to where you want the shirt to fall. Most people prefer 2–3″ below the waistband.
🧺
Heavy cotton may shrink slightly after the first wash. Wash at 30°C to preserve the print and minimise shrinkage.
⚠️
Baseball jerseys are baggy by design — measurements in inches are garment measurements. Your actual chest should be 8–12″ smaller than the shirt chest listed. If you prefer a more fitted look, size down 1–2 sizes.
