Sizing info is a required product dimension bullet on Bloomingdale's Marketplace for the kids and baby dresses department. Bloomingdale's uses it to tell a shopper, in a fixed phrase, whether a dress runs small, large or true to size. Without it, a kids and baby dresses listing is incomplete and Osello will not submit it. The value appears in the details section of the product page.
The rules
| Rule | Value |
|---|---|
| Required | Yes |
| Maximum length | 254 characters, spaces included |
| Form | One of Bloomingdale's set phrases, no trailing period |
| Level | Parent listing, one value for the whole style |
| Department | Kids and baby dresses |
The value has to be one of these, spelled exactly:
| Phrase | Meaning |
|---|---|
| Fits small, order one size up | The dress runs tight for its labeled size |
| Fits large, order one size down | The dress runs roomy for its labeled size |
| Fits true to size, order your normal size | The dress matches its labeled size |
No model size, no measurements, no second phrase, no period. The bullet lives on the parent listing and Bloomingdale's shows one set of bullets for the whole grouping, so it describes the style, never a single color or size.
Deciding how a dress runs
Start with the fit guidance in your own product data. A "runs small" note in the description or a fit metafield decides the phrase on its own. When your data has no guidance, read the fit notes, silhouette, fabric stretch and images:
- A fitted, structured or non-stretch dress, such as a woven party dress with a fitted bodice and back zipper, runs small.
- An oversized, boxy or relaxed dress, such as a loose knit shift or a tunic-style dress, runs large.
- A dress with no signal either way is true to size.
Baby dresses carry the same phrases. A dress with a snap or envelope opening built for easy dressing is usually true to size; a fitted smocked bodice with no stretch is the typical "fits small" case.
Examples
| Value | Verdict | Reason |
|---|---|---|
| Fits true to size, order your normal size | Good | The default phrase, spelled exactly |
| Fits small, order one size up | Good | Right for a non-stretch fitted bodice |
| Fits large, order one size down | Good | Right for a relaxed knit shift |
| Order a size up | Weak | Not one of Bloomingdale's phrases |
| Fits true to size, model wears 6X | Weak | Adds a model size |
| Fits small in 12M, true to size in 2T and up | Weak | Describes individual sizes |
| Fits true to size, order your normal size. | Weak | Trailing period |
| Chest 22 in, length 20 in | Weak | Measurements belong in the size chart |
Common mistakes
- Rewording the phrase. Bloomingdale's wants its exact text.
- Adding a model size or garment measurement. Use the Size Chart Image for those.
- Describing one size range of a style. Pick the phrase that fits the style as a whole.
- Leaving the field blank when there is no fit data. "Fits true to size, order your normal size" is the default.
- Mixing up this field with Silhouette or Length, which describe the shape and hem rather than the fit.

How Osello fills this field
Osello treats Sizing info as a required parent-level text field capped at 254 characters and shows it once the listing is in a kids and baby dresses category. When the listing is filled in, the AI reads the product description first, then the attributes, then the images, and selects one of the set phrases, defaulting to "Fits true to size, order your normal size" when nothing indicates a different fit. The value is written once per style and shared by every size and colorway. Each AI value carries a confidence score, so a phrase inferred from images alone is flagged for a quick review. The listing stays not ready until the field has a value, as described in required fields and listing readiness. If your fit guidance lives in a Shopify metafield, point the AI at it with custom instructions.
Frequently asked questions
Is Sizing info required for kids and baby dresses on Bloomingdale's?
Yes. It is a required product dimension in this department, and Osello blocks submission until it has a value.
Which phrases are allowed?
"Fits small, order one size up", "Fits large, order one size down" and "Fits true to size, order your normal size", with the exact spelling and no trailing period.
What if I have no fit information for a dress?
Enter "Fits true to size, order your normal size". Osello uses the same default when the description, attributes and images give no signal.
Can I mention the model's size?
No. The value is one of the set phrases and nothing else. Model details belong in the description or size chart.
Does each size of a dress get its own Sizing info?
No. The field is set once on the parent listing and shared by every size and colorway of the style.
