What it's worth new vs used
Used kids' costumes sold for a median of $18, no less than the $18 new with tags fetched (85 sales). The two groups are made of different brands and styles, so tags alone do not set the price here.
How it compares
Of the 30 kids' categories with enough sales for a page, this one has the 8th highest used median. Used women's costumes sold for $20 (38 sales), 11% more than kids'. Used baby costumes sold for $36 (90 sales), 100% more than kids'. Across every department, including unisex and untagged listings, the used median is $20.50 from 630 sales. The spread is wide: one in ten sold for $9 or less and one in ten for $45 or more, so brand matters a great deal. A branded item is better valued from its own sales. 98% 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 kids' 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.
