# Bloomingdale's Measurements based on size X (Women's Jeans, Women's Pants & Capris, Women's Shorts and 1 more) Field Guide

> All measurements based on size X. Max character limit of 254 characters (including spaces).

**Measurements based on size X** is an optional size and fit bullet on Bloomingdale's Marketplace for the women's bottoms department. It gives the garment's length in inches and names the size it was measured on, so a shopper can compare the number against a piece they already own. Bloomingdale's shows it in the details section of the product page. The field is one of the shared size and fit attributes Macy's Inc. defines across departments, and it is set per variant rather than once per style.

## The rules

| Rule | Value |
| --- | --- |
| Required | No |
| Maximum length | 254 characters, spaces included |
| Form | One phrase with the "Approx." prefix, no trailing period |
| Level | Variant, each size can carry its own measurement |
| Department | Women's bottoms |

The shared definition fixes the wording for the garments it names:

| Garment | Form |
| --- | --- |
| Jumpsuits, rompers and other one-pieces | Approx. X" from back of neck to hem, based on a size Y |
| Jackets, blazers, coats, dresses | Approx. X" from back of neck to hem, based on a size Y |
| Tops, tees, blouses, sweaters | Approx. X" from high point shoulder to hem, based on a size Y |

For pants, jeans and shorts the length is already covered by [Inseam Type & Measurement](/marketplaces/bloomingdales/fields/product-dimensions4-womens-bottoms). Where this bullet is filled on a skirt or a one-piece in the women's bottoms department, Osello recommends the same pattern with the measurement point that fits the garment ("Approx. 24" from waist to hem, based on a size 27" for a skirt). Take the number from the size chart or your product measurements; with neither, the instructions call for an estimate from the garment type and silhouette that keeps the "Approx." label. Never write TK or another placeholder.

## Examples

| Value | Verdict | Reason |
| --- | --- | --- |
| Approx. 56" from back of neck to hem, based on a size 6 | Good | The fixed one-piece form |
| Approx. 24" from waist to hem, based on a size 27 | Good | Skirt length with the reference size |
| Approx. 18" from waist to hem, based on a size S | Good | Works with alpha sizes |
| 24 inches | Weak | No measurement point, no size |
| Length: TK | Weak | A placeholder |
| Approx. 22" to 26" from waist to hem | Weak | A range; give each size its own value |
| Hits above the knee. | Weak | Descriptive, no number, ends with a period |

## Common mistakes

- Repeating the inseam here for pants. Inseam has its own required bullet.
- Writing one measurement at the parent level. The field lives on each variant so the length can grow with the size.
- Dropping "Approx." or the "based on a size" clause.
- Shipping a placeholder because the size chart is missing.

## How Osello fills this field

Osello treats Measurements based on size X 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 first, then the product description and attributes, then the images, and writes the length with the fixed wording and the reference size. Each size variant gets its own value; there is no parent value to fall back on. When no measurement exists, it estimates from the garment type and silhouette and keeps the "Approx." label rather than leaving a placeholder. See [what gets filled in automatically](/help/channels-listings/what-gets-filled-in-automatically) and [confidence scores explained](/help/ai-prompts/confidence-scores-explained) for how an estimated value is flagged for review.

## Frequently asked questions

### Is Measurements based on size X required for women's bottoms on Bloomingdale's?

No. Bloomingdale's marks it optional in this department, and pants carry their length in Inseam Type & Measurement instead.

### Which size do I reference?

The size the garment was measured on, usually the base size in your size chart, written as "based on a size 27".

### Why is the field set per size?

Garment length changes with the size, so Bloomingdale's takes the bullet at the variant level. Each size can show its own number.

### What if I have no measurement?

Osello estimates from the garment type and silhouette and keeps the "Approx." label. Review the value before submitting, or add the measurement to your size chart so the estimate is replaced.
