Sizing Information on Bloomingdale's Marketplace is the one-line fit verdict a shopper reads before choosing a size: does this panty run small, run large or fit true to size. This page covers the version of the field in the women's panties department (briefs, bikinis, thongs, boyshorts, hipsters and shapewear bottoms). The field is required, it sits on the parent listing so one value covers every colorway and size, and Bloomingdale's shows it as a feature bullet on the product page.
The field is unusual among Bloomingdale's attributes in that the wording is fixed. Bloomingdale's supplies the exact phrases and the value has to be one of them, so this is not a place to write your own fit copy. Intimates are a high-return category, and a consistent sentence across every brand is how Bloomingdale's lets shoppers compare fit at a glance.
The rules
| Rule | Value |
|---|---|
| Required | Yes, in women's panties |
| Length | At most 254 characters, spaces included |
| Form | One of Bloomingdale's phrases, no trailing period |
| Level | Parent listing, shared by every variant in the style group |
| Content | The fit verdict only; no model size, no measurements |
The accepted phrases
| How the item runs | Enter exactly |
|---|---|
| Runs small | Fits small, order one size up |
| Runs large | Fits large, order one size down |
| Runs as expected | Fits true to size, order your normal size |
Spelling, capitalization and punctuation follow the table. "Runs small", "Size up" and "True to size" are the same idea in different words and none of them is accepted.
Deciding which phrase applies
Use the brand's own fit guidance first. Most intimates brands publish a fit note in the product description, the size chart or the attributes, and the note maps directly to one of the phrases. When there is no note, the silhouette and the fabric decide:
| Signal in the source data or images | Likely verdict |
|---|---|
| Fitted, structured, non-stretch, compression or bodycon | Fits small, order one size up |
| Oversized, boxy, relaxed or generous cut | Fits large, order one size down |
| Standard stretch knit with no fit notes | Fits true to size, order your normal size |
When nothing points either way, "Fits true to size, order your normal size" is the default. Shapewear deserves a closer look than everyday panties: compression styles often run small by design, and the brand's fit note usually says so.
Examples
| Value | Verdict | Reason |
|---|---|---|
| Fits true to size, order your normal size | Good | Exact phrase |
| Fits small, order one size up | Good | Exact phrase, right for a firm-control brief |
| Fits large, order one size down | Good | Exact phrase |
| Runs small | Weak | Not one of the accepted phrases |
| True to size. Model wears size M | Weak | Adds the model size and a period |
| Fits true to size; waist measures 26 to 28 inches | Weak | Measurements belong elsewhere |
| Fits small in the Black colorway | Weak | Describes one color |
| Order your usual size, it fits great | Weak | Rewritten copy |
Common mistakes
- Paraphrasing the phrase. Bloomingdale's wants its wording, character for character.
- Adding the model's size or height. That has its own field, Model's Measurements & wearing a size X.
- Adding measurements or the size range. The Size Chart Image carries them.
- Leaving the field blank because the brand has no fit note. The field is required; use the default.
- Choosing "Fits small" for every shapewear piece by reflex. Check the brand's note, since light-control styles often fit true to size.
- Ending with a period.
How Osello fills this field
Osello treats Sizing Information as a required text field on the parent listing for items placed in a women's panties category on Bloomingdale's. The AI agent reads the product description first, then the attributes, and picks the Bloomingdale's phrase that matches the brand's fit guidance. With no guidance it infers the verdict from the fit notes, silhouette and fabric stretch described in the source and defaults to "Fits true to size, order your normal size". It never adds a model size or a measurement. The value is set once per style group and mirrored to every colorway and size. See required fields and listing readiness and how Osello AI fills listing fields. If a brand has a house rule for fit, such as always sizing up its shapewear, custom instructions let you tell the agent once.
The same field, with the same phrases, is required for tops, bottoms, dresses, outerwear, active bottoms and jumpsuits, and optional for sports bras. Other panties fields are Rise Type and Gusset, and everything else is in the Bloomingdale's field directory.
Frequently asked questions
Is Sizing Information required for women's panties on Bloomingdale's?
Yes. Every panty listing needs one of the accepted phrases, and a blank field keeps the listing from being complete.
Can I write my own fit description?
No. The value has to be "Fits small, order one size up", "Fits large, order one size down" or "Fits true to size, order your normal size", exactly as written.
The brand has no fit guidance. Which phrase do I use?
Judge from the silhouette and fabric: firm, non-stretch or compression styles usually fit small, relaxed cuts fit large. If nothing points either way, use "Fits true to size, order your normal size".
Where do the model's size and the measurements go?
The model's height and size go in Model's Measurements & wearing a size X, and body measurements go on the size chart. This field holds the fit verdict alone.
Can different sizes in one style have different fit verdicts?
No. The field lives on the parent listing and every variant shares it. If a brand says its plus range fits differently from its core range, the two ranges belong in separate style groups.
