How to Measure
To find your ideal U.S. Polo Assn. size, take accurate body measurements using a flexible tape measure while wearing lightweight clothing. Follow these steps:
- Chest / Bust: Measure around the widest part of your chest, just below the armpit and over the shoulder blades, keeping the tape measure horizontal and comfortably snug — not too tight.
- Waist: Measure around your natural waistline where your trouser waistband would comfortably sit, typically just above the belly button. Keep the tape snug but not constricting.
- Hips: Measure around the fullest part of your hips and bottom, keeping the measuring tape as horizontal as possible.
- Inside Leg: Measure straight down the inside of the leg from the crotch to the ankle bone for trousers, or to your preferred length for shorts.
- Sleeve Length (Long Sleeve): Measure from the centre back at the spine, along the shoulder and down the arm to the wrist bone with your arm slightly bent.
- Neck: Measure around the base of the neck where a shirt collar would sit comfortably. Allow enough room to insert two fingers between the tape and your neck.
- Thigh: Measure around the fullest part of your upper leg, just below the crotch.
