How selling kidswear wholesale works
Kidswear sells wholesale to children's boutiques, baby and gift stores, and department stores. A store buys by age group, so one style can run from 0–3 months to 24 months in baby sizes, or from 2 to 14 years for kids.
Stores buy in prepacks across the size run, reorder basics such as bodysuits and leggings often, and plan around back-to-school and holiday as well as spring and fall. Safety matters too: in the US, children's products need third-party testing and a Children's Product Certificate before they are sold.
The work is keeping age-based size runs and prepacks right on every order and making the basics reorder fast. Our guide to the prepack explains how packs work across a size run.
What ModaFlow.ai does for childrenswear brands
Size runs by age
Set up 0–3M to 24M, 2T to 5T, 2 to 14 years or any run you sell, and every style shows its own sizes in the order grid.
Collections by age group
Put baby, toddler and kids' styles in their own collections, each with its own line sheet, lookbook and order minimum.
Prepacks across the run
Offer a 1-2-2-1 prepack across 2 to 8 years or a case of six bodysuits, and ModaFlow checks it on every order before it is accepted.
Basics on reorder
Stores reorder bodysuits and leggings from a past order in your portal, at current prices, in a couple of taps.
Line sheets from your catalog
Export a line sheet PDF for each collection with photos, colourways, sizes, wholesale price, MSRP and minimums.
Ship windows for every season
Every order carries a ship window and a cancel date, so back-to-school and holiday orders land when the store needs them.
Kidswear line sheet example
A kidswear line sheet groups styles by age group, shows the full size run and prepack for each, and puts the season and ship window at the top. Compare layouts in our line sheet examples, start from the free line sheet template, or see how line sheet software turns the sheet into orders.

See plansFrequently asked questions
Can one style run from baby to kids' sizes?
Yes. A size run can hold up to 60 sizes, so a style can go from 0–3 months to 14 years. Most brands keep baby and kids' sizes as separate styles, because stores buy them for different departments.
Can stores order prepacks and single sizes?
Yes. A buyer adds a prepack in one tap and changes single sizes in the order grid, and ModaFlow checks the style's minimum, case pack and order multiple before the order is accepted.
Where do I mention safety testing?
Mention testing in the style's description, which buyers read in your portal and shared lookbooks, and keep the certificates themselves in your own files to send when a store asks.
What does ModaFlow not do for childrenswear brands?
It does not store safety certificates, attach them to line sheets, or record tracking-label and batch details, so keep those records in your own files. Your catalog, line sheets, lookbooks, buyer portal and orders all live in ModaFlow.
