The Best Buy & Sell Sites For Children’s Clothes

Naturally, a child’s wardrobe will evolve as they grow but thanks to a range of new platforms, it’s never been easier to give out-grown, unwanted clothes a second lease of life. From high-street gems to the luxury collective worth having on your radar, here are the sites and resellers to know about.

Kidswear Collective 

Established in 2018, Kidswear Collective is an online store offering pre-loved and past-season designer children’s fashion. With a luxury brand roster including Stella McCartney Kids, Chloé, Burberry and Gucci – as well as small, up-and-coming labels – everything on the website is sourced, curated and authenticated by an exclusive industry network. The brand also donates 2.5% of all proceeds to the NSPCC. 

Kids O’Clock 

After working with the likes of Moda Operandi, Ralph Lauren, NET-A-PORTER and Harvey Nichols, and nine months after the birth of her son, Laura Roso Vidrequin launched Kids O'Clock. The platform is now a trusted space to shop and sell pre-loved children’s items. As well as taking advantage of the seamless selling process, you can also buy beautiful pre-loved pieces from brands like Caramel, Tartine et Chocolat and Jacadi. 

Wunder Duds 

Wunder Duds is a marketplace that makes it easy to buy and sell pre-loved kids’ clothing, reduce unnecessary waste and keep clothing in the circular economy. If you’re looking to sell, simply choose between listing the clothes yourself or sending them in. If you’re looking to make a purchase, an edit of re-loved pieces includes mini Vejas and La Coqueta cardigans. 


Co-founders Louise and Sam both felt overwhelmed by how fast their kids grew out of clothes – and how few accessible and circular solutions there were for selling them on. Their mission to change that resulted in Dotte, a simple one-stop-shop where parents can buy, sell, donate and recycle children's clothing. The brand also goes beyond the peer-to-peer buying and selling model by offering community donation and recycling options, too. 

Mini Boden Preloved 

Mini Boden Preloved was founded by mum-of-three, Liz Smith. Her love for the iconic British brand – as well as extending the life cycle of clothes – prompted her to set up the website and run regular market nights via the brand’s Facebook page. She also regularly lists items on Instagram. Easy to navigate and purse-friendly, there are plenty of options for ages six months right through to 13 years.
