Buying kids’ clothing in Seattle
Seattle pairs a large technology workforce with a serious outdoor culture and a genuinely wet climate.
Age labels correspond only loosely to any actual child, and two garments marked the same can differ by a good few centimetres. Holding something against the child it is meant for settles that at once, which no size chart manages.
What to check in person
Go through a bundle piece by piece rather than accepting a count, since the bottom of a bag is where the tired items sit. Hold pale colours to the light for the food and grass marks that photographs never pick up.
Collecting it in Seattle
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.
The city is hilly and the water divides it, so the bridge or the route matters more than the distance. Parking in the denser neighbourhoods is difficult, and a lot of handovers happen at park-and-ride lots for that reason.
Selling your kids’ clothing in Seattle free
Technology hiring moves people in and out, and outdoor gear runs on its own upgrade cycle — equipment gets bought, used for a couple of seasons and passed on in good condition when someone moves up a level.
Sell it as a bundle by age and say how many pieces are included and what they are. Photograph everything laid out together, and be honest about any marks, because parents buying second hand expect wear and price it in. 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.
