My daughter lived in the COTTO set all summer - I washed it twice a week and it still feels like day one. At this price, I actually bought backups.

The one-size concept is a game changer. My 2 year old and 4 year old can actually share the LOMI shirts without them looking weird.

Finally, a brand that doesn't use scratchy labels. My son has sensitive skin and the ELIRA dress is the only thing she doesn't try to pull off.

The herringbone texture on the ELIRA is so premium. It looks like a boutique find but handles playground dirt like a pro.

The FLORELLE set is incredibly breathable. Perfect for humid afternoons when everything else sticks to their skin.

I love that I don't have to keep a 'next size up' bin in the closet anymore. One-size is the smartest thing I've bought this year.
