Sizing Information is a required size and fit attribute on Bloomingdale's Marketplace for the women's dresses department. It tells the shopper whether a dress runs small, large or true to size, in one of the exact phrases Bloomingdale's has standardized across its site. The bullet sits with the other fit details on the product page, and a women's dress listing without it is incomplete and will not pass into review.
Bloomingdale's Marketplace runs on Mirakl and shares its size and fit definitions with Macy's. Each apparel department has its own version of this field; this page covers women's dresses. The same required attribute exists for women's tops and women's bottoms.
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 of Bloomingdale's exact phrases, no trailing period |
| Content | Fit direction only; no model size, measurements or fabric notes |
The accepted phrases
| Fit | Phrase to enter |
|---|---|
| Runs small | Fits small, order one size up |
| Runs large | Fits large, order one size down |
| Standard | Fits true to size, order your normal size |
Use the phrase as written. Rewording it ("runs a little small", "size up for a relaxed look") breaks the consistency shoppers rely on when they compare dresses across brands on Bloomingdale's, and it does not tell the customer what to do at the size selector. Because the value lives on the parent listing, one phrase covers every colorway and size of the dress.
Deciding which phrase fits
Start with your own fit guidance: fit notes from the technical designer, returns data that says customers size up, or the fit line already in your product copy. When the source says nothing, the silhouette and fabric are the next best signal. A fitted, structured, non-stretch or bodycon dress tends to run small; an oversized, boxy or relaxed dress tends to run large. With no reason to pick either, "Fits true to size, order your normal size" is the default.
Keep the other size and fit fields separate. How the dress fits at the bust, hip and waist belongs in Bust, Hip, Waist Fit Details, how much the fabric gives belongs in Fabric Stretch/Give, and the model's height and size belong in Model's Measurements & wearing a size X.
Examples
| Value | Verdict | Reason |
|---|---|---|
| Fits true to size, order your normal size | Good | Exact phrase |
| Fits small, order one size up | Good | Exact phrase for a fitted, non-stretch dress |
| Runs small | Weak | Not one of the accepted phrases, no instruction |
| True to size. | Weak | Shortened and ends with a period |
| Fits true to size; model is 5'9" wearing size S | Weak | Adds model details that belong in another field |
| Order one size up in the navy | Weak | Fit guidance for a single colorway |
Common mistakes
- Leaving the field empty because you have no fit data. The field is required; default to "Fits true to size, order your normal size".
- Paraphrasing the phrase. Enter it exactly.
- Attaching measurements or fabric notes. Those have their own fields.
- Giving different fit guidance per colorway. The value is set once for the whole dress.
How Osello fills this field
Osello treats Sizing Information 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 chooses one of the exact phrases. It uses the brand's fit guidance when the source has it; otherwise it infers from fit notes, silhouette, fabric stretch and imagery, and falls back to "Fits true to size, order your normal size". The result is at most 254 characters with no trailing period. Each AI-filled value carries a confidence score, so a phrase inferred from silhouette alone is easy to spot and review, and a brand that always wants a particular default can say so in custom instructions.
Frequently asked questions
Is Sizing Information required for dresses on Bloomingdale's?
Yes. Every women's dress listing needs one of the accepted phrases before submission.
Can I write my own fit sentence?
No. Bloomingdale's standardizes this bullet on "Fits small, order one size up", "Fits large, order one size down" or "Fits true to size, order your normal size". Anything else should be reworded to one of them.
Which phrase do I use when I have no fit data?
"Fits true to size, order your normal size". Switch to fits small or fits large only when the fit notes, returns or silhouette give a reason.
Where do model height and garment measurements go?
Model height and size worn go in Model's Measurements & wearing a size X; garment length goes in Dress Length based on size X. Sizing Information carries only the fit direction.
