Classic Fit and Tailored Fit describe different Peter Millar cuts, even when the size chart shows the same chest range. Do not assume that a shared Medium label means the finished shirts have identical room. Start from the body-size guidance, then choose the cut that gives you the silhouette and movement you want.
The official examples here are ETC Stripe in Classic Fit and Beam Performance Mesh in Tailored Fit. They illustrate the fit descriptions; their different fabrics mean they are not a controlled fabric comparison.

Use the chart to identify a starting size
The Classic Fit example and Tailored Fit example show the same chest ranges for the sizes listed above. That is a useful reminder that the size guide and the amount of ease built into a shirt answer different questions.
Measure according to the brand’s current instructions and avoid tightening the tape to reach a preferred label. If your measurements fall between ranges, ask for guidance on the exact polo. A general internet rule to size up or down can change shoulder position, sleeve length and body length as well as chest room.
Do not turn the chart into a finished-shirt measurement
A chest range used for size selection should not be halved and presented as a guaranteed pit-to-pit width. If you need finished garment dimensions, ask the seller to measure the actual style and define the endpoints. Compare like with like: a flat width, a circumference and a body measurement are different records.
Lay a polo you already like flat without stretching it and record its width and length separately. That reference can help a retailer advise you, but it should not override the product’s own measurement method. Keep the style and fabric of the reference shirt in your notes.
Check where the cut changes your movement
Try reaching forward, taking your golf stance and sitting. Notice whether the fabric pulls across the back or chest and whether the sleeve opening catches during movement. A neat standing fit can still feel restrictive when you reach for a club.
For Classic Fit, check whether the extra room hangs as you prefer or gathers beneath a layer. For Tailored Fit, check whether the closer shape remains comfortable without needing to size up solely to escape one tight area. If neither works, another polo shape can be a better solution than forcing a label.
Choose the fit with your normal outfit
Wear the trousers and belt height you normally use, then assess the hem tucked or untucked as appropriate for your course. Compare the collar beneath your usual pullover. Those details are easier to judge together than from separate product photographs.
Our golf clothing guide covers outfit basics, and the apparel brand overview gives broader alternatives. For Peter Millar, keep the conclusion specific: the cut and size that work in one exact polo, not a permanent rule that every Classic or Tailored garment fits you the same way.
Before buying, verify the style code and current return conditions. Keep tags attached during an allowed fitting, and save the successful model details for the next order.
