With asymmetric hem (AH): Approx. TK” from back of neck to longest point of hem, based on a size TK

 Max character limit of 254 characters (including spaces).

**Dress Length based on size X** is a required fit bullet in Bloomingdale's women's dresses department. It gives the approximate garment length in inches, the point it was measured from, and the size it was measured on. Bloomingdale's shows it in the size and fit section of the product page, and a women's dresses listing cannot be submitted from Osello until the field has a value. A shopper who knows a 36" dress hits her at the knee will trust that number more than a "midi" label.

## The rules

| Rule | Value |
| --- | --- |
| Required | Yes |
| Maximum length | 254 characters, spaces included |
| Unit | Inches, marked with a straight double quote (36") |
| Form | One of Bloomingdale's formats, with the sample size filled in |
| Level | Parent listing, one value for the whole style |
| Department | Women's dresses |

## The accepted formats

Bloomingdale's asks for one of its own sentence templates, with the measurement and the size in place of the placeholders. Its template text uses "TK" for each placeholder; the value you submit never contains "TK".

| Situation | Format |
| --- | --- |
| Standard dress | Approx. 36" from back of neck to hem (BNTH), based on a size 4 |
| Asymmetric hem | With asymmetric hem (AH): Approx. 40" from back of neck to longest point of hem, based on a size 4 |
| Sample size only | Sample size: 4 |

Dresses, jumpsuits, jackets and coats measure from the back of the neck to the hem. Tops measure from the high point shoulder to the hem, which is why the same department family uses that wording elsewhere. When the brand supplies an exact measurement or a size chart, use it. When it does not, an estimate from the garment category, the silhouette in the images and the fit notes is acceptable and expected; the field is never left blank and never filled with placeholder text.

## Examples

| Value | Verdict | Reason |
| --- | --- | --- |
| Approx. 35" from back of neck to hem (BNTH), based on a size 4 | Good | Standard format, sample size filled in |
| With asymmetric hem (AH): Approx. 42" from back of neck to longest point of hem, based on a size 6 | Good | Asymmetric format, longest point stated |
| Approx. 58" from back of neck to hem, based on a size 8 | Good | Maxi, format without the abbreviation is also accepted |
| Midi length | Weak | No measurement or size |
| Approx. TK" from back of neck to hem, based on a size TK | Weak | Placeholders left in |
| 36 inches | Weak | No measurement point or size |
| Length varies by size | Weak | The bullet is a single sample size |

## Common mistakes

- Leaving the field blank because there is no tech pack. Estimate from the category and the images, and refine when the measurement arrives.
- Quoting the model's height or size here. Those belong in [Model's Measurements & wearing a size X](/marketplaces/bloomingdales/fields/product-dimensions5-womens-dresses).
- Measuring an asymmetric hem at the shortest point. Bloomingdale's wants the longest point, in the asymmetric format.
- Using the top format. "From high point shoulder to hem" is for tops; dresses measure from the back of the neck.

## How Osello fills this field

Osello treats Dress Length based on size X as a required parent-level text field capped at 254 characters. When a women's dresses listing is filled in, the AI takes the exact length from the source data or size chart when one exists, and otherwise estimates it from the garment category, the silhouette in the images and the fit notes, then writes it in the back-of-neck-to-hem format with the sample size. It never leaves the field blank, never writes a placeholder and never adds a note about the estimate. The value is set once per style and shared by every size and colorway. Because the field is required, the listing shows as not ready until it has a value; see [required fields and listing readiness](/help/channels-listings/required-fields-and-listing-readiness). A low [confidence score](/help/ai-prompts/confidence-scores-explained) flags an estimated length for a quick check before submission.

## Frequently asked questions

### Is Dress Length based on size X required for women's dresses on Bloomingdale's?

Yes. It is a required fit bullet in this department, and Osello will not submit the listing without it.

### What if I do not have an exact measurement?

Estimate it. Bloomingdale's format allows an approximate value, and an estimate from the category and the images is expected when exact data is missing. Replace it with the measured length when you have one.

### Which size should the measurement be based on?

The sample size the brand measured, or the size the images show. State it at the end of the phrase, for example "based on a size 4".

### How do I write a high-low or asymmetric hem?

Use the asymmetric format and measure to the longest point of the hem: "With asymmetric hem (AH): Approx. 40" from back of neck to longest point of hem, based on a size 4".
