# Bloomingdale's Support & Construction (Women's Dresses) Field Guide

> Underwire support, shelf bra, boning and location, etc. Max character limit of 254 characters (including spaces).

**Support & Construction** is a required feature attribute on Bloomingdale's Marketplace for the women's dresses department. It tells the shopper what is built into the dress to hold its shape and support the bust: underwire, a shelf bra, molded or lined cups, boning and where the boning sits. Bloomingdale's shows the value as a feature bullet, and because it is required, a women's dress listing without it is incomplete and will not pass into review.

Bloomingdale's Marketplace runs on Mirakl and shares its attribute definitions with Macy's. The definition comes from the intimates world, where the same attribute is required on [women's bras](/marketplaces/bloomingdales/fields/fnb4-womens-bras). On dresses it matters most for strapless, formal, swim-adjacent and bodycon styles, where a shopper decides based on whether she can skip a bra.

## The rules

| Rule | Detail |
| --- | --- |
| Required | Yes |
| Level | Parent listing, one value shared by every color and size |
| Length | Up to 254 characters, spaces included |
| Format | One phrase, no trailing period |
| Content | Support level and construction: underwire or wireless, cups, boning and location, shaping |

Cover what the dress has: underwire or wireless; light, medium or full support; lined, unlined or molded cups; a built-in shelf bra; boning and its location (side seams, bodice); shaping or structured construction. Because the field is required, a dress with no support features still needs an honest value that says so; Osello's recommendation is a plain phrase such as "No built-in support" or "Unstructured bodice, no built-in support". The value applies to every colorway and size.

## Examples

| Value | Verdict | Reason |
| --- | --- | --- |
| Built-in shelf bra with light support | Good | Construction plus support level |
| Underwire cups with side boning | Good | Support and the boning location |
| Structured bodice with boning at the side seams | Good | Construction detail a strapless shopper needs |
| Molded cups, wireless | Good | Cups and wire status |
| No built-in support | Good | Honest value for a dress without support features |
| Supportive fit. | Weak | Vague, a period, no construction |
| Bra-friendly | Weak | Says nothing about what is built in |

## Common mistakes

- Leaving the field empty on a dress without support. The field is required; state that there is none.
- Writing "boning" without the location. Bloomingdale's asks where it sits.
- Putting lining here. Whether the dress is lined goes in [Lining](/marketplaces/bloomingdales/fields/fnb11-womens-dresses); this field is about support structure.
- Describing the fabric's compression as support unless the dress has an actual shaping construction.

## How Osello fills this field

Osello treats Support & Construction as a required, parent-level text field on Bloomingdale's women's dress listings, so one phrase is shared by every variant. The AI reads the product description first, then the attributes, then the images, and writes one phrase of at most 254 characters with no trailing period. When the source states or shows no support features at all, the field stays blank and the listing shows as incomplete until someone supplies a value; see [required fields and listing readiness](/help/channels-listings/required-fields-and-listing-readiness). A brand that wants a standard phrase for unsupported dresses can set it in [custom instructions](/help/ai-prompts/custom-instructions).

## Frequently asked questions

### Is Support & Construction required for dresses on Bloomingdale's?

Yes. Every women's dress listing needs a value before submission, including dresses with no built-in support.

### What do I enter for a simple knit dress with no bra or boning?

A plain statement such as "No built-in support". An empty field blocks submission; an honest phrase does not.

### Is a lined bodice the same as support?

No. Lining is coverage and belongs in the Lining field. Support means underwire, cups, a shelf bra, boning or shaping construction.

### Where do the support details for a swim dress go?

In this field, with the intimates vocabulary: "Underwire, full support, lined cups" or "Wireless, light support, removable cups".
