Lacoste sizing depends on silhouette: the women’s chart is a useful starting point, but slim, regular, relaxed and oversized cuts call for different choices. This guide compares the chart with Lacoste and Nordstrom fit notes across polos, tees and sweaters.

Lacoste Sizing: Does Lacoste Run Small, Big or True to Size?
The chart is only a starting point
Lacoste sizing depends on the silhouette, so I would not size every polo, tee and sweater by one rule. For the lacoste size chart, use the women's section: it runs from XS through XL, maps those labels to EU sizes, and lists bust, waist, low-hip and arm measurements. Bust runs from 78 cm for XS to 107 to 112 cm for XL, so measuring is more useful than borrowing a size from another garment. The brand's Regular Fit Supple Petit Piqué Polo is a straight 100% cotton shape and advises choosing the larger size when between sizes. Its Oversized Cotton Poplin Shirt points the other way: one size down for a closer fit. The L.12.D Slim Fit Stretch Mini Piqué Polo sits close, while Lacoste describes its Soft Cotton T-Shirt and cotton crew-neck sweater as relaxed. At Nordstrom, the Gender Inclusive Solid Cotton Polo says true to size, and the Loose Fit Cotton French Terry Sweatshirt does too. A chart number should narrow the options, not settle the fit question. I would measure, pick the amount of ease I want, then follow the advice attached to that exact product.
Polos in distinct cuts
Polos first: four different cuts make it clear why Lacoste does not have one universal sizing rule. The brand's Regular Fit Supple Petit Piqué Polo is a straight cut, and its product advice says to choose the larger size if you fall between two. The L.12.D Slim Fit Stretch Mini Piqué Polo is closer to the body, so start from the chart and decide if you want that shape to skim or fit close rather than sizing down automatically. Nordstrom's x BANDIER Slim Fit Piqué Polo gives another slim option; the Gender Inclusive Solid Cotton Polo page says true to size. That retailer note is a useful anchor, but the brand's own measurements still matter because body measurements are not the same as a garment's ease. For a first order, compare bust first, then decide whether shoulder and sleeve room should be close or relaxed. The label is not a substitute for checking fit advice on the exact polo.
Tees and casual tops
T-shirts and casual tops are less consistent than a size label makes them sound. The brand's Relaxed Fit Soft Cotton T-Shirt is the looser tee, while Oversized Cotton Poplin Shirt is cut with more volume and Lacoste advises one size down for a closer fit. Nordstrom's Ribbed Cotton Blend Tank has selectable sizes from XS through XXL, so the range can differ at another retailer; the Loose Fit Cotton French Terry Sweatshirt lists sizes L, XXL and 3XL and a true-to-size note. These are separate pieces, not a conversion chart: a roomy sweatshirt does not tell you how a fitted tank will feel. I would use the body chart to pick the starting point, then check sleeve length, shoulder shape and torso room on the exact product. If between sizes, follow the poplin shirt's instruction only when you want less of its intended volume. For the tank, the retailer page's selectable sizes and the item description are the useful checks.
Sweaters and soft layers
Knits add one more reason to read details instead of trusting a memory of another Lacoste item. The Relaxed Fit Cotton Crew Neck Sweater has a relaxed shape, while the Wool High-Neck Sweater is a wool layer with a different neckline; Nordstrom's Cashmere Blend Cardigan offers a button-front layer, and the Gender Inclusive Crocodile Badge Loose Fit Crewneck is true to size according to its page. The cardigan's available size and the crewneck's remaining size can change, so treat the displayed options as a live snapshot. My recommendation is to use the tape measure, choose your preferred ease, and follow product-specific advice: up between sizes for the regular polo, down one for a closer oversized shirt, and true-to-size notes only for styles that actually say so. If polos are the goal, start with the chart and fit note; if sweaters are the goal, compare their shape and the layer underneath before ordering.
