For donations

A donor itemizing a used baby costume with no brand to go on could use $36, the 12-month median for used baby costumes, or $36 for one in good condition (62 sales). A branded item is better valued from its own sales.

Method: the median final sold price of 90 used baby costumes sold on Poshmark (US) from Aug 14, 2026 to Oct 11, 2026, from SoldStack's archive of 168,038 categorized sold listings, computed Oct 23, 2026. Bundles, lots and non-clothing listings are left out.

This is resale market data, not tax or legal advice. For US donors, the IRS requires a qualified appraisal (Form 8283, Section B) when a single item, or a group of similar items, is claimed at over $5,000.

The 2026 Donated Clothing Value Guide has every category and condition as a CSV. To value a whole list item by item, with brands, paste it into the list demo.

What it's worth new vs used

Only 16 baby costumes sold new with tags in the last 12 months, fewer than 30, so there is no new-against-used comparison here. Used items are what most donors give, and the used figure above stands on its own.

How it compares

Of the 10 baby categories with enough sales for a page, this one has the 1st highest used median. Used women's costumes sold for $20 (38 sales), 44% less than baby. Used kids' costumes sold for $18 (121 sales), 50% less than baby. Across every department, including unisex and untagged listings, the used median is $20.50 from 630 sales. 99% of the used sales were listed in good condition or better.

How these values are worked out

Each sale in SoldStack's archive is tagged with a department and a category from its title, brand and size. This page takes every Poshmark (US) sale tagged baby and costumes, leaves out lots, bundles and listings with no condition, and gives the median final sold price: half sold for more, half for less. "Used" is every worn grade, new without tags down to fair. Sold prices are the last listed price, so an accepted offer may have been a little lower, and a thrift store would usually charge less than an online sale. The numbers are recomputed from the archive every hour. How the tags were checked is on the accuracy page.
