What Is Sizing Like at Lacoste mens?

Lacoste runs trimmer than you'd expect and uses French sizing, so a classic polo comes cut a touch shorter in the body and slimmer through the shoulders and sleeves than the American labels most men are used to. Put simply: it's a proper European fit, and the number on the label doesn't behave like an S/M/L.

That's the headline. Now here's everything you actually need to know before you buy the crocodile.

The numbered sizing, explained

Lacoste's polos and shirts are sold on a numeric scale rather than letters, and that trips up more men than anything else. As a rough guide:

2 = XS, 3 = S, 4 = M, 5 = L, 6 = XL, 7 = XXL, 8 = 3XL
The numbers follow your chest measurement, so measure across the fullest part and go by that, not by what you "usually" are.
Footwear and tailoring lean on EU sizing too, so always convert rather than eyeball it.

The classic polo: the fit reality

The iconic petit piqué polo is the piece 90% of people are here for, so let's be honest about how it wears:

Structured, not slouchy. The piqué cotton is firm and has very little give, so it won't relax into you the way a soft jersey tee does. Buy the fit you want on day one.
Shorter in the body. Cut for European proportions, it sits right at the waist. Taller men who like to tuck should size the length carefully.
Trim shoulders and sleeves. The seams sit closer to your actual shoulder and the arms are cut lean, which flatters an athletic frame but can pinch broader chaps.

Classic vs Slim vs Loose

Lacoste sells the same polo in a few silhouettes, and choosing the right one matters more than the size:

Classic Fit — the roomiest of the three and the closest to UK sizing. Best for a relaxed, wear-anywhere look.
Slim Fit (L.12.12) — noticeably narrower in the chest and waist with shorter sleeves. Sharp under a blazer, unforgiving if you're not lean.
Loose / relaxed — the newer oversized cut for a modern, casual drape. Size down if you don't want it swamping you.

Beyond the polo

T-shirts: Lacoste Live runs fitted and cropped; Lacoste Sport is looser and longer. Pick your range to pick your fit.
Trousers & chinos: mid-rise with a little stretch, but often a shade snug at the waist. If you're between sizes, size up.
Tracksuits & hoodies: broadly true to size, though tall men should check the arm length.
Trainers (Carnaby, Powercourt, Graduate): true to size to half a size small, and cut narrow. Wide feet should go up half a size; leather pairs feel tight at first, then break in.

A quick word from experience

Early in my career I bought myself a Lacoste polo in my "usual" large for a summer wedding, assuming it would drop long and easy like a Ralph Lauren. It rode up out of my waistband the moment I sat down, and I spent the day tugging it. Lesson learned. These days I always check the body length, not just the chest, and when I dressed a client for a shoot last year I sized him into a classic 5 that looked immaculate — crisp shoulders, clean hem, no fuss. Trust the number and the fit name, and Lacoste rewards you.

Where else to look

If Lacoste's cut isn't quite your shape, these are the brands I'd send you to instead across every budget:

High street

Fred Perry — the natural British rival with the same tennis DNA. Its twin-tipped polo runs slim and true to size, so it's the closest swap if you like Lacoste's tailored feel.
Ralph Lauren — the roomier, longer American preppy option. Ideal if you found Lacoste too short or too snug in the arms.
Ben Sherman — smart mod styling and well-priced Oxford shirts and polos, cut a little more generously through the body.
Farah — brilliant for lean, retro-leaning smart-casual, especially the slim trousers and knitted polos.

Independent & boutique

Sunspel — the connoisseur's polo. Beautifully finished British piqué with a cleaner, more considered cut than the mainstream names.
Percival — a playful London label doing knitted and camp-collar polos with real personality, great if you want smart-casual with a twist.
Drake's — heritage London tailoring energy in soft, relaxed polos and knitwear; a step up in cloth and drape.

Designer & luxury

Orlebar Brown — the resort-smart benchmark. Its polos are cut sharp and sit beautifully with tailored shorts.
Brunello Cucinelli — quietly luxurious Italian knitted polos with a soft, elegant hand that reads as expensive without shouting.
Loro Piana — the top of the tree for cloth. If you want the finest cotton and cashmere-blend polos money can buy, this is it.
