Leg Opening Measurements is an optional size and fit bullet on Bloomingdale's Marketplace for the women's bottoms department. It gives the circumference of the leg opening in inches, with the size the measurement was taken on. Bloomingdale's shows it in the details section of the product page, where it helps a shopper judge how a straight, wide-leg or skinny pant will sit over a boot or a sneaker. Unlike most bullets in this department, the field is set per variant rather than once per style.
The rules
| Rule | Value |
|---|---|
| Required | No |
| Maximum length | 254 characters, spaces included |
| Form | One phrase, no trailing period |
| Level | Variant, each size can carry its own measurement |
| Department | Women's bottoms |
Write the measurement in inches, prefixed with "Approx.", and add the size it is based on when you know it: "Approx. 16" leg opening, based on a size 27". Take the number from your product measurements or size chart. When neither gives a leg opening, leave the field blank; do not estimate it from the silhouette.
Examples
| Value | Verdict | Reason |
|---|---|---|
| Approx. 16" leg opening, based on a size 27 | Good | Measurement and reference size |
| Approx. 22" leg opening, based on a size M | Good | Works with alpha sizes |
| Approx. 12" leg opening | Good | Measurement without a known size |
| 16 | Weak | No unit, no context |
| Leg opening: narrow | Weak | A description, not a measurement |
| Approx. 16" to 20" leg opening | Weak | A range across sizes; give each size its own value |
| Fits over boots. | Weak | A sentence with a period, no measurement |
Common mistakes
- Putting the leg silhouette here. Skinny, straight or wide leg belongs in Leg Silhouette.
- Giving one number for the whole size run at the parent level. The field lives on each variant so that a size 32 can show a larger opening than a size 25.
- Dropping the inch mark or the "Approx." prefix.
- Mixing up leg opening and inseam. Inseam has its own bullet, Inseam Type & Measurement.
How Osello fills this field
Osello treats Leg Opening Measurements as an optional variant-level text field capped at 254 characters. When a women's bottoms listing is filled in, the AI reads each variant's measurements and the size chart, then the product description and attributes, and writes the leg opening for that size with the "Approx." prefix and the reference size. Each size variant gets its own value; there is no shared parent value to fall back on. When neither the source data nor the size chart states a leg opening, the field stays blank. See what gets filled in automatically and using Shopify metafields if your measurements live in metafields.
Frequently asked questions
Is Leg Opening Measurements required for women's bottoms on Bloomingdale's?
No. It is optional and stays blank when your measurements do not include a leg opening.
Why is the field set per size?
The leg opening grows with the size, so Bloomingdale's takes it at the variant level. Each size can show its own measurement instead of one number for the style.
Which size do I reference?
The size the measurement was taken on, written as "based on a size 27". If you only have the measurement, give it on its own.
Can I estimate the leg opening from the photos?
No. Use a measured value from your product data or size chart, or leave the field blank.
