Peter Millar Sizing and Fit Guide

Peter Millar offers three distinct fits—Classic, Tour, and Performance—and sizing varies by garment type. For the best fit, measure your chest, waist, hips, and inseam in inches, then compare against the specific product’s size chart. If you’re between sizes, your choice of fit and how you plan to wear the piece (e.g., layering vs. wearing alone) will determine whether to size up or down. For example, a Crown Crafted polo in Medium Classic fit comfortably accommodates a 41-inch chest, while the same chest measurement in Medium Tour fit would feel restrictive.

What You’ll Need Before You Order

• A soft cloth tape measure (metal tapes don’t bend around your body)
• A notepad to record measurements in inches
• The size chart on the exact product page you’re buying (Peter Millar’s charts differ slightly by garment, even within the same fit category)

Measure on bare skin or against a thin base layer like a t-shirt. Avoid bulky sweaters or layers that add 1–2 inches of padding. A common error is measuring over a tailored dress shirt, which already has its own ease.

How to Measure in 4 Steps

1. Chest – Wrap the tape around the fullest part of your chest, just under your armpits and across the shoulder blades. Keep the tape level and snug but not tight. Write down the number where the tape overlaps.

Tip: have a friend help if you’re unsure. A self-measurement often adds 1–2 inches because you pull the tape across your back at an angle.

2. Waist – Measure around your natural waistline, about an inch above your belly button. The tape should fit comfortably without digging in. For a golf polo, this is less critical because the hem is usually below the belt line.

3. Hips (for bottoms and long jackets) – Measure around the widest part of your hips, roughly 8 inches below your waist. This matters for the Grange Quarter Zip or any outerwear that covers the hips.

4. Inseam – For pants, stand with your legs slightly apart and run the tape from the top of your inner thigh down to your ankle bone. Repeat on the other leg and use the longer measurement. Peter Millar’s pants (e.g., the Crown Crafted Woven Short or Performance Tapered Pant) list inseam in 2-inch increments (30, 32, 34).

Record all four numbers. You’ll use these to match against the chart on the product page, not a generic “Medium” label.

What to Do If Your Measurements Fall Between Two Sizes

This is the most common sizing decision. Your next move depends on the fit style and how you intend to wear the garment.

Example 1: Chest measures 41 inches.

The size chart for a Crown Crafted Tour fit polo shows Medium for 38–40 chest and Large for 42–44.

• Choose Large in Tour fit. The extra half-inch in chest won’t leave you swimming in fabric, and it keeps the shoulders from pulling when you swing a club.
• Choose Medium in Classic fit. Classic fit already has 1–2 extra inches of ease through the body, so your 41-inch chest will be comfortable without looking baggy. A Medium Classic fit polo in the Crown Crafted line fits a 41-inch chest with about 1 inch of ease around the midsection.

Example 2: Waist measures 33 inches.

Peter Millar pants are labeled by waist size (e.g., 32 fits 31–32, 34 fits 33–34). Choose 34. Their waists run true to size with minimal stretch, so a 32 will likely feel snug after the first wear and may leave red marks.

Example 3: Outerwear layering.

If you plan to wear a Grange Quarter Zip (Performance fit) over a polo and a light sweater, size up one from your normal chest size. For example, if you wear a Large in Peter Millar polos, order an XL in the Grange Quarter Zip. The underlayer adds about an inch of bulk, and the Performance fit has minimal spare room.

Fit Differences Across Garment Lines

Not all Peter Millar garments with the same fit label behave identically. The Crown Crafted line uses a slightly softer fabric that drapes looser compared to the Sahara line, which is a firmer cotton blend. A Medium in Crown Crafted Classic fit may feel similar to a Medium in Sahara Classic fit, but the Sahara polo will hold its shape more rigidly, so it may feel tighter if your chest is near the upper boundary of the size.

For outerwear like the Grange Quarter Zip (Performance fit), the sleeves are intentionally cut longer to allow full shoulder rotation during a golf swing. If the sleeves reach your wrist bone when your arms are at your sides, that’s correct—they will shorten by about 1.5 inches when you extend your arms forward.

Checking the Fit After You Receive the Garment

Try the item on with the clothing you’ll normally wear underneath. For a polo or button-down, verify these three points:

• Shoulder seams – They should sit right at the edge of your shoulder bone, not drooping down your arm or riding up. If you can see the seam beyond your shoulder point, the shirt is too wide.
• Chest and back – The fabric should lie flat when you cross your arms or raise them to shoulder height. Horizontal wrinkles across the back or pulling at the button line mean the shirt is too small. For a Tour fit polo, slight tension across the lats is normal but should not restrict movement.
• Hem length – The front hem should fall just below your belt line. If it hits mid-belt or higher, the shirt is too short. Peter Millar polos are designed to stay tucked during a swing, so a hem that barely covers the belt is acceptable for golf.

For pants, check the waist and seat. The waist should hold without a belt but not dig in. If you need to hold your breath to button them, size up.

Common Mistake: Choosing Tour Fit When You Have Broad Shoulders

The symptom: A Tour fit polo fits your chest and waist perfectly, but when you swing a club or reach forward, the fabric pulls tight across your shoulder blades. The collar may feel like it’s choking when you button the top button.

Likely cause: Tour fit is trimmed through the shoulder yoke compared to Classic. If your shoulder measurement is proportionally wider than your chest, the shirt can’t expand enough.

Better next move: If you already own the shirt, stop wearing it for golf and return it within the 30-day window. For your next order, go up one size in Tour fit (e.g., Large instead of Medium) or switch to Classic fit in your original size. The Crown Crafted polo in Classic fit adds about 2 inches of shoulder room in the same chest size, as measured from the shoulder seam to the collar.

When to Stop DIY and Seek an Exchange or Refund

You should stop trying to make a size work if any of these conditions are true:

• The garment is uncomfortable when you stand still, not just during movement.
• You need to hold your breath to button the waist on pants or the top button on a collar.
• The sleeves are more than 2 inches above or below your wrist bone when your arms are at your sides.

Concrete threshold: If a polo or shirt causes red marks on your shoulders or neck after wearing it for 10 minutes, do not try to stretch it out or wash it to shrink. Peter Millar’s return policy allows exchanges within 30 days of purchase as long as tags are attached and the item is unworn or only tried on. Use this window rather than forcing a bad fit. For items bought at a pro shop or authorized retailer, the same window applies—keep the original receipt.

Take your chest, waist, hips, and inseam measurements before ordering. Check the product-specific size chart and fit description. If you are between sizes, use the branch guidance above based on your fit choice and layering needs. After the garment arrives, test the three fit checkpoints—shoulder seams, chest/back movement, and hem length—before cutting tags. That combination will get you a reliable fit the first time.
