Calling All Wild Hearts: Your Size Guide is Here

Wild Hearts is here—bold, untamed, and made for the fearless. This collection isn’t just about what you wear—it’s about how you live . Rooted in independence and unapologetic self-expression, Wild Hearts blends western charm with modern femininity in a way that’s uniquely you.


With a fiery palette of bold reds, punchy pinks, and rodeo inspired elements, these pieces embody the confidence, charisma, and wild spirit that lives in all of us. Inspired by open plains, desert sunsets, and wildflower trails, Wild Hearts celebrates those who live life wide open and untamed —because outlaws don’t follow trends, they create them.


We know that feeling confident in your clothes starts with the right fit , especially when it comes to pieces that are designed to move with you - through life, motherhood, and every wild ride in between.

Our Wild Hearts collection introduces four bold new styles , designed with mums in mind and made for everyday ease, versatility, and confidence . Each piece is breastfeeding-friendly , proving that functionality can absolutely be stylish and empowering.


👢 The Slouchy Tee

🌵 The Indie Maxi Dress


A flowing, feminine silhouette with adjustable front ties , the Indie Maxi is your go-to for those golden-hour moments. The tie-front makes it perfect for breastfeeding , while the relaxed shape keeps it bump and postpartum-friendly , too.

A fresh take on the classic Lacey Shirt, Billie features two front ties instead of buttons that offer easy feeding access and a relaxed, flattering shape. Wear it open over a tank, or tie it up solo for that effortlessly cool western vibe. It’s functional, comfy, and full of attitude.


The Lilly Vest


Tailored yet versatile , the Lilly Vest features functional buttons and adjustable corset back, making it a stylish option for breastfeeding . Layer it or wear it solo - either way, it adds instant polish to your Wild Hearts look.

How To Measure For Our Size Guide

1. WAIST: For measuring the waist first button the pants up. Next spread the pants flat on the surface, and remove any fullness and wrinkles from it.


3. HIP: Measure across the hip area


5. LENGTH (outter seam): With the pants buttoned up, spread the pants on a table, floor or any other flat surface, with outseams on both corners. After removing all wrinkles and any fullness, measure the length from the top of the waistband.
