Style in Sync: The Cutest Matching Sibling Outfits for Spring & Summer

here’s something undeniably sweet about siblings in coordinated looks—and even more so when the outfits are as comfortable as they are stylish. That’s why we’re excited to introduce new girls’ pieces designed to pair perfectly with two of your favorite boys’ sets: the Jackson Set and the Luca Set.

These effortless combinations take the guesswork out of styling siblings, offering head-to-toe outfits that are playful, polished, and perfect for family photos, park days, or just everyday twinning. If you’ve been looking for the ideal matching sibling outfits, these sets are it.

The Jackson Set + Demi Jumpsuit & Olivia Romper

Cool, Bold, and Built for Play

The Jackson Set—already a fan favorite—is known for its black lightning bolt print, a bold and playful pattern that boys love. Made from ultra-soft fabric with a relaxed fit, it’s ideal for active days and big personalities. To complement it, we created two new coordinating girls' pieces: the Demi Jumpsuit and the Olivia Romper.

Demi Jumpsuit – This modern, easy-to-wear one-piece mirrors the cool factor of the Jackson Set while adding a refined twist for older girls.
Olivia Romper – A short, sweet romper designed for little sisters who want in on the fun.

Together, these styles make one of our most versatile matching sibling outfits—perfect for siblings close in age or spanning a few years. Whether it’s for a weekend outing or just running around the backyard, this trio has style and comfort to spare.

The Luca Set + Valentina Dress

Sporty, Soft, and Preppy Perfection

The Luca Set has become a warm-weather staple thanks to its soft terry fabric and playful checkered pattern. It's relaxed, breathable, and stylish—everything a boys’ set should be. To match its sporty-casual vibe, we created the Valentina Dress, a new girls' style with a tennis dress silhouette that's as functional as it is fashionable.

Luca Set – Lightweight terry with a checkered texture for effortless style.
Valentina Dress – A modern tennis dress that’s sporty, structured, and just the right amount of preppy.

This set is made for sunny outings, family brunches, or any moment when you want your kids to look coordinated without compromising comfort. It’s an elevated take on matching sibling outfits with a fresh, athletic twist.
