Our leggings are handmade to order by us in England. These are made from a cotton jersey knit of 95% cotton 5% Elastane. All Our Fabrics are Oko-Tex Standard 100 certified to ensure they are gentle on little people. Being a mum of boys we know how durable leggings need to be, this is why all seams are overlocked to create a quality and durable product. Our leggings have a slightly baggy feel in order to ensure your little one can move and play with ease, exactly as they should. As we know not all children are the same, should you feel your little one would benefit from a wider leg we offer this at no extra cost, just let us know when you place your order. All leggings have an ankle cuff to keep them close to the skin and out of the mud. I also love that it means if your child is like mine and has perfected the roll away while getting dressed it means the trousers stay on!. The cuff is also reversible which means it can be turned up or down depending on the height of your child. In order to keep them at their best we advise turning our leggings inside out and washing at a low temperature (30 degrees) then air drying. Sizes 0-3 months - 18-24 months inclusive are cut for nappies (disposable and cloth) and from 2 years upwards they are cut prodomiantely for pants, these will still work with disposable nappies due to the stretch however should you wish for extra room just ask for wider cut when you order. Size 5-6 have no outside seam.
