When your little one seems to be in a continual growth spurt, keeping them clothed is a never-ending challenge. If the full-length pants you buy for your child somehow become capris in a matter of weeks, let us introduce you to the future of children’s clothing: garments that grow. Designed by Ryan Mario Yasin, a London-based aeronautical engineer who specializes in deployable structures, the Petit Pli line of children’s clothing is made of pleated fabric that stretches with your child. The genius design means that the same shirt or pair of pants can expand to accommodate seven different sizes, so that the same piece can last one child for years. Siblings can even (comfortably) share the same wardrobe. This is the real-life Sisterhood of the Traveling Pants.

The innovative collection was inspired by Yasin’s niece and nephew, who would outgrow the clothing the designer would buy for them before he even had a chance to gift them. Not only does the flexibility of this clothing make it easier to gift, but think about the money parents will save by not having to buy a new wardrobe in every size. The line also works to reduce environmental waste by limiting the number of garments that end up in the landfill.

Currently, the company is focusing on outerwear and is developing a wind- and waterproof outer shell. Made of durable synthetic fabrics, the pieces are machine-washable and can be air-dried. And thanks to the permanently-pleated design, they never need to be ironed.

The line isn’t available for sale just yet, but you can join the Petit Pli mailing list to be the first to know when it launches. Until then, watch this extraordinary clothing in action.
