And not only are they super cute (loads of styles have been adapted from the main line), but they also reflect McCartney’s ethical values — tops and bottoms are made with organic or sustainable fabrics.

“I wanted this first collection to include basic pieces that are comfortable and that address a child’s needs, without sacrificing the fun and carefree elements,” shared the soon-to-be mom-of-four.

Standouts include the wool Lee Band Jacket ($145), the floral-print Lydia Blouse ($68) and the cashmere/wool blend Ash Jumpsuit ($88).

Added bonus: A percentage of online sales of the the organic cotton Leo Sweatshirt ($36) will help benefit dad Paul McCartney‘s organization, Meat Free Monday.
