The Kooples uses a sizing system that does not always correspond to the usual benchmarks of French ready-to-wear. A size 38 from this brand may fit differently than a size 38 purchased elsewhere, with variations depending on the category of clothing and the collection. Before finalizing an online cart, it is better to understand the brand’s specific sizing logic rather than relying on your usual size.
The Kooples Double Size Chart: 0-1-2-3 Rating and French Equivalence
One point that most guides overlook: The Kooples increasingly employs a double sizing system in its recent collections. Some models display sizes numbered 0, 1, 2, 3, 4, while others retain the classic system of 34, 36, 38, 40, 42. This coexistence of two size charts on the same site creates real confusion at the time of purchase.

In older collections, only the French size appeared. New product listings tend to show both systems in parallel, with a direct correspondence (0 = XS/34, 1 = S/36, 2 = M/38, etc.). The problem arises when a buyer orders from the second-hand market or during clearance: the label often only shows one of the two systems, without an accessible conversion chart.
To know how The Kooples fits for men and women, you first need to identify which of the two systems applies to the targeted model, then compare it with your own measurements rather than your usual size at Zara or Sandro.

Actual Lengths on Product Listings: An Underutilized Indicator
Field feedback varies on this point: some buyers find that The Kooples runs small, while others believe the sizing is true to size. Part of these contradictions can be explained by the length of the pieces, which is rarely taken into account in discussions about sizing.
The brand’s recent product listings are starting to mention precise length data. For example, a long tulle dress is indicated to be 135 cm long for a size 36, with a straight cut and smocked empire waist. This type of information changes the game for women measuring less than 1.60 m or more than 1.75 m.
Most competing items settle for a binary verdict (“runs small” or “true to size”) without addressing this vertical dimension. Checking the total length of the garment on the product listing, when available, avoids many disappointments, especially with dresses, coats, and structured blazers.
The Kooples Sport: Unisex Pieces That Change the Sizing Logic
The The Kooples Sport line introduces an additional parameter. Unlike the main collections separated by gender, this range features predominantly unisex pieces (joggers, sweatshirts, oversized t-shirts). The sizing chart works differently here.
On a unisex piece, the sizing is generally calibrated on a male basis. A woman who usually wears M in The Kooples women’s collection will often need to go down to S in the Sport line to achieve a comparable fit. The available data does not allow for conclusions about the entire Sport range, as cuts vary from season to season.
Practical Guidelines for Unisex Pieces
- A unisex sweatshirt in size S generally corresponds to a women’s M and a men’s S in the classic collection
- Sport joggers have a straighter cut than women’s pants, with an inseam calibrated to male proportions
- The oversized t-shirts in this line are designed to fall loosely: taking your usual size gives a deliberately ample look, while going down a size tightens the silhouette
Variations Between Collections and Second-Hand The Kooples Pitfalls
A The Kooples blazer purchased in 2019 does not fit the same as a blazer from the 2025 collection bearing the same label. Cuts evolve from season to season, sometimes significantly, depending on creative inspirations and pattern adjustments.
This phenomenon poses a concrete problem for the second-hand market, which is growing for this brand. Resale platforms rarely display the collection year, and individual sellers often only mention the label size. Two size 38 jackets produced three years apart may show differences in shoulder or waist measurements.
How to Limit Errors in the Second-Hand Market
- Ask the seller for the product reference or article code found on the inner label, which allows you to find the original listing on The Kooples’ website
- Compare flat measurements (shoulder width, back length, chest circumference) rather than relying on the displayed size
- Check if the model belongs to the classic line, Sport, or a capsule series, as each follows its own cutting logic
Taking Measurements for The Kooples: Key Measurement Points
The brand’s official guide details the correspondences by category (tops, bottoms, dresses, belts, shoes) for men and women. The key measurements to take are bust circumference, waist circumference, and hip circumference. But one point deserves to be highlighted: shoulder width often determines the final choice on The Kooples jackets and blazers, as the brand’s structured cuts allow little room for deviations at this level.
For men, neck circumference is a useful reference for shirts, while inseam remains the discriminating criterion for pants. Field feedback shows that The Kooples men’s pants tend to offer an inseam slightly shorter than the average of the French premium market.
The best approach remains to measure a well-fitted garment already present in your wardrobe, then compare these flat measurements with those from the official guide. This method neutralizes variations between brands and collections, and works well for both in-store and online purchases.
