# Bloomingdale's Sizing info (Baby Polo Shirts, Baby Shirts, Baby Sweaters and 30 more) Field Guide

> Fits small, order one size up / Fits large, order one size down / Fits true to size, order your normal size. Max character limit of 254 characters (including spaces).

**Sizing info** tells a Bloomingdale's shopper whether a kids' or baby top runs small, large or true to size. It is a required size-and-fit attribute for the Kids & Baby tops department, so a listing in that department will not pass Bloomingdale's checks without it. The value is displayed on the product page, and it does more to cut returns than almost any other attribute, because a parent ordering for a growing child wants to know whether to size up.

Bloomingdale's does not accept free text here. The answer has to be one of its own phrases.

## The allowed values

| Phrase | Use it when |
| --- | --- |
| Fits small, order one size up | The top is fitted, structured, non-stretch or runs snug |
| Fits large, order one size down | The top is oversized, boxy or relaxed |
| Fits true to size, order your normal size | Neither applies, or you have no fit guidance |

The phrase must be copied exactly, with the comma and without a trailing period. Do not add a model's size, body measurements or garment measurements; those belong in the other size-and-fit fields. The limit is 254 characters, which no allowed phrase comes close to.

## Rules at a glance

| Rule | Value |
| --- | --- |

| Format | One of the three Bloomingdale's phrases, verbatim |
| Never include | Measurements, model stats, a size chart, a color or size reference |

## Kids & Baby tops compared with other departments

Bloomingdale's asks the same question in other departments under slightly different names. The Women's active bottoms version is called [Sizing Information](/marketplaces/bloomingdales/fields/product-dimensions1-womens-active-bottoms) and takes the same three phrases. For kids and baby items, the fit question is usually decided by whether the size is labeled by age, by height or by a letter size, and by how much room the cut leaves for growth, so a brand that cuts generously should say so with "Fits large, order one size down".

## Examples

| Value | Verdict | Reason |
| --- | --- | --- |
| Fits true to size, order your normal size | Good | Exact Bloomingdale's phrase |
| Fits small, order one size up | Good | Exact phrase, right for a slim knit tee |
| Runs small | Weak | Not one of the accepted phrases |
| Fits true to size. Model wears size 5. | Weak | Adds model information and a period |
| True to size for most kids, order up if between sizes | Weak | Rewrites the phrase |

## Common mistakes

- Paraphrasing. "Runs true to size" is not the same as "Fits true to size, order your normal size".
- Leaving the field empty because the brand has no fit study. Default to the true-to-size phrase.
- Filling it with a size chart or a "measured on size" note. Those go in the measurement attributes.
- Changing the answer per color. Fit is a property of the style.

## How Osello fills this field

Osello fills this required parent-level field once per style. It looks for fit guidance in the product description and attributes first, such as a "runs small" note or a "relaxed fit" label. With no explicit guidance it infers the answer from the silhouette, fabric stretch and images, treating fitted, structured or non-stretch tops as running small and oversized, boxy or relaxed tops as running large, and falls back to "Fits true to size, order your normal size". The output is always one of the three exact phrases. See [how Osello AI fills listing fields](/help/ai-prompts/how-osello-ai-fills-listing-fields) for the general process and [required fields and listing readiness](/help/channels-listings/required-fields-and-listing-readiness) for how a missing value blocks submission.

## Frequently asked questions

### Can I write my own fit sentence?

No. Bloomingdale's accepts only its three phrases: "Fits small, order one size up", "Fits large, order one size down" and "Fits true to size, order your normal size". Anything else risks rejection during review.

### What do I put if I have no fit data?

Use "Fits true to size, order your normal size". It is the default when nothing in the product suggests the top runs small or large.

### Is Sizing info the same field as Sizing Information?

They are separate fields with the same purpose in different Bloomingdale's departments. This one belongs to Kids & Baby tops. Both use the same three phrases.

### Can the answer differ between colors of the same top?

No. The field lives on the parent listing and covers every colorway and size of the style.
