Second-hand kids’ clothing in St Louis typically sells for $7 to $47. The very small sizes turn over fastest because babies pass through them in weeks, leaving barely worn stock. School uniform answers to term dates instead, and the same items are worth noticeably more in August than in November.
Buying kids’ clothing in St Louis
St Louis sits below the confluence of the two great rivers with an arch on the waterfront that is the tallest monument in the country. It has a substantial brewing and manufacturing history, several universities and a great deal of brick housing stock.
Children’s clothing is outgrown rather than worn out, so it comes onto the local market in genuinely good condition and usually in bundles. Buying a stage at a time from someone a few streets away is far cheaper than buying it new.
What to check in person
Look at how many washes the fabric has had, judged by bobbling and faded colour rather than by the label. Check elastic at waists and cuffs still recovers, and make sure school items carry the right badge for the school you actually need.
Collecting it in St Louis
It fits in a bag, so most people meet on the way to something else. A station or a high street works, and neither side needs a car.
Driving is assumed and the city is spread out. Older brick housing has narrow stairwells, so measure the turn rather than the doorway for anything large.

Industrial decline left tooling in private hands, and the universities clear student housing each May. The old brick housing stock brings genuinely old furniture onto the market.
Wash and fold everything before it is seen, since a neatly presented bundle sells for noticeably more than the same clothes in a bag. Separate by size rather than mixing ages, because a parent is shopping for one child at one stage. Moves in waves as each school year turns over, with a clear lift before September.
Peer-to-peer payment apps dominate private sales, and buyers will usually offer one before they offer cash. Sales tax does not apply to a private sale between individuals.
