Size Guide
Ready-to-use version - separate CM and INCH tables - fitted, straight, loose, and oversized cuts
|
Before Ordering The tables are body measurement guides. They do not replace the exact measurements of the finished garment. For a structured, loose, oversized, limited edition, or custom-made item, the measurements indicated on the product sheet and the workshop's advice remain priority. |
CM / INCH Conversion
|
Rule |
Application |
|
1 inch = 2.54 cm |
Values in inches are calculated from centimeters and rounded to the nearest tenth. |
|
1 cm = 0.3937 in |
Inches help UK / US / international customers find their way. |
|
Main reference Ousman O. |
France / Europe + body measurements in cm. Inches remain a complementary reference. |
How to take your measurements?
Take your measurements standing up, without tightening the tape measure. For a structured or close-fitting garment, it is best to measure yourself with the underwear or thin clothes you will wear with the item.

Understanding Ousman O. fits
This section is important for loose or oversized garments: the volume can be intentional and part of the style envisioned by the workshop. Therefore, the indicated size should not be considered alone; the fit and measurements of the finished garment must also be checked.
Fit guide
|
Fit |
Meaning for the customer |
Sizing advice |
|
Fitted |
Close-fitting, precise silhouette, little ease. |
Take your usual size. If you are between two sizes, contact the workshop or choose the next size up for more comfort. |
|
Straight |
Balanced fit, neither tight nor loose. |
Take your usual size. Check chest, waist and hips according to the product. |
|
Loose |
More comfort and movement, visible but controlled volume. |
Take your usual size to maintain the intended ease. Only take one size down if you prefer a more fitted look. |
|
Oversized |
Deliberately generous volume, wider shoulders or body. |
Take your usual size for the designer effect. Take one size down for a more subtle effect, if the product description allows. |
|
Structured / Tailored |
Built shoulders, armholes, collar or volume. |
Check the measurements of the finished garment: shoulder width, flat chest width, arm circumference, sleeve length and back length. |
|
Collection piece or limited edition |
Unique piece or produced in very small series. |
Availability and reproduction to be confirmed. Contact the workshop before ordering if the size is not clear. |
|
Recommended phrase for oversized product descriptions The oversized cut is intentional. Choose your usual size to maintain the volume designed by the workshop; choose one size down only if you want a more understated fit and if the product description recommends it. |
Women's Size Guide
These tables provide body measurement references. For couture dresses, tailored jackets, and high-fashion pieces, the choice also depends on the desired ease, the material, and the exact measurements of the finished garment.

Men's size guide
The men's chart distinguishes between jackets/coats, shirts, and trousers. Jacket size mainly follows chest circumference, shirt size also follows neck circumference, arm circumference, and wrist circumference, and trouser size follows waist circumference, hips, and inseam.

Workshop advice For structured men's garments, upper arm ease and shoulder width are important, especially if the garment is worn with a shirt or a thin sweater. |
Finished garment measurements to be indicated on product sheets
The general guide helps in choosing a size, but finished garment measurements are essential for loose, oversized, structured, or limited-edition items. On Shopify, add this information to each product sheet, ideally in cm and inches.
