oh-my-measure brand size charts

496 size charts published by 132 clothing brands (EU, FR, INT, IT, JP, RU, UK, US), transcribed from each brand's own size guide and normalised into a single long-format table of 9132 rows.

Read this first: rights

No licence is granted over these numbers, and none is claimed.

The numbers are facts about goods a brand sells — what chest girth size 40 means in that shop. They are not our work, so we do not license them from our own name: not CC BY-SA, not CC0, not anything. Granting a licence means disposing of a right, and the rights here are not ours.

This is exactly why this dataset is published separately from oh-my-measure-size-grids, which does travel under CC BY-SA 4.0. Mixing them would extend that statement over material it cannot cover.

What is ours — the selection, the cross-checking, the normalisation and the shape of this export — we also claim nothing over. Take it.

Brand names are used nominatively, to say whose chart it is. If you hold rights and think a chart should not be here, say so and it will be removed — every row carries grid_id, so withdrawing one brand is deleting its rows and rebuilding.

Full statement: RIGHTS.txt.

Why long format

496 charts are heterogeneous by column: one brand prints bust, waist and hip, another prints bust only. A single wide table would pad empty columns down the full height; one file per chart would mean 992 files.

In long form a row is (chart, label, measure) and a missing measure simply produces no row — rather than an empty cell a consumer has to tell apart from zero. Pivot it back if you want width:

import pandas as pd
df = pd.read_csv("brand-grids.csv")
wide = df.pivot_table(index=["grid_id", "label"], columns="measure",
                      values=["low_cm", "high_cm"])

Files

File	What
brand-grids.csv	the long table — grid_id, brand, brand_name, system, cut, label, alpha, measure, low_cm, high_cm
brands.csv	registry — name, group, country, homepage, size-guide URL, chart count
passports.json	per-chart provenance: source URL, capture date, prose in 4 languages
datapackage.json	Frictionless manifest
RIGHTS.txt	the rights statement in full
DATASET-README.txt	the Russian-language README shipped with the export

Join brand-grids.csv → passports.json on grid_id, and → brands.csv on brand. Provenance sits apart because repeating a source paragraph on each of 9132 rows would serve nobody.

Units

Girths in centimetres — that is how the sources print them. Column names say so (low_cm, high_cm).

Provenance

Every chart names its source URL and its capture date. All 504 sources carry both.

Not included

Brands with no transcribed chart — the app's catalogue is longer, but a claim about numbers is more expensive to earn than a claim about existence. Bras, footwear and accessories are out of scope: different measures.
