Cheap designer kids' clothes

In addition to sustainable fashion brands for kids like Batoko (which makes amazing swimsuits out of recycled water bottles) parents are also buying their children's wardrobes from a bevy of online shops, with designer brands like Stella McCartney, Wild & Gorgeous and Ralph Lauren and big reductions to be had. Many of these companies also allow parents to send in their unwanted kids' clothes, instead of having them go to waste.

Kidswear Collective
Founded by Shoshana Kazab, a kidswear industry pro who represents lusted-after labels like Aden + Anais, Rachel Riley and Il Gufo through her PR agency, Fuse Communications, Kidswear Collective offers up to 80% off pre-loved designer gear for kids from birth to 14 (and you get an extra 20% off your first order). The comprehensive selection also offers accessories like bibs, blankets, socks and bags. Expect brands from Balenciaga to Baby Dior, Chloe to Catimini, as well as kidswear faves like Mini Rodini. For those whose shopping method of preference involves Insta curation, that's covered too: mum and child influencers like Emma & Alf and The Fashion Bug Blog have their own dedicated pages of clothes you can buy from their personal wardrobes. Also, there's an option to purchase new, designer items from last season, not just pre-loved clothing.

Littlest Luxuries
Beautifully curated like your favourite online shop (there are even Summer and Winter sections), Littlest Luxuries can kit your child out from birth to 12+ with its charming selection of baby gear (Bonpoint all-in-ones, Liberty prints from Caramel Baby and Jacadi), girls' and boys' clothes and must-have accessories, including Gucci Princetown silver metallic loafers for £90. After you've filled your shopping basket with summer florals and kids' wedding looks (snag a smart boys' blazer from Bonpoint for £40), you can even sort out next year's ski wardrobe with parkas from top brands like Woolrich, Moncler and Finger in the Nose. Happy shopping!

Treasure House
Our go-to brand for designer kids' clothes on the cheap, Treasure House often pops up in London neighbourhoods (we discovered the brand at a sale at a local mum's house). With boys' and girls' clothes from birth through age 16, they've got you covered both in terms of must-have designer brands like Burberry and Gucci - dresses range from £20-£60 - as well as labels like Italian-made Harmont and Blaine (you can currently stock up on their range of boys' shirts for just £2 a pop). Treasure House has a trade-in policy so you can send in your own gently used kids' clothes in exchange for shopping credit. As if you needed further enticement, you also get an extra 25% off your first order.

Loopster
Founded by Jane Fellner, a mum with firsthand experience of the garment industry from her time working in Bangladesh as a filmmaker, Loopster makes it easy for parents to offload clothing they no longer need - and get paid for it, if the quality is good enough (if not, clothes will be donated to a charity shop like Traid or returned to you). The site has girls' and boys' clothes from baby through age 8, from designer brands like Little Marc Jacobs and Paul Smith as well as beloved French brands like Petit Bateau, Catimini, Bonpoint and Jacadi, with many items £15 and under. You'll also find a selection of high street on the ultra cheap - an M&S dress for £3.50, a Gap hoodie for £6. When you think that it takes a mind-boggling 10,000-20,000 litres of water to make just one pair of jeans - which produce 23.2 kilos of CO2e in the process - then you'll wonder why you haven't been getting secondhand Zara, or Stella, for that matter, trousers this whole time.
