Timeless jumpsuits, no age limits.
Hello Friends!
We’re Isabella and Rachel — cousins, BFFs, and now co-founders of Butter and Birthday Cake! Our journey began with shared laughter, complementary jumpsuits, and silly photographs that quickly became treasured memories. It all started because we simply adored dressing alike - turning family gatherings into fashion moments and everyday adventures into something special.
In fact, our playful nicknames, Butter (Isabella) and Birthday Cake (Rachel), were lovingly created by Butter herself when she was just five years old - names that stuck because they captured our unique bond so perfectly!
Fashion, for us, is deeply personal. It’s about family, friendship and the joy of being coordinated. Inspired by one of our favorite photos of us wearing complimentary coveralls, we decided to create something truly special - high-end, vintage-inspired jumpsuits for adults and kids, each one crafted to be as unique and memorable as the people wearing them.
Butter & Birthday Cake isn’t just about beautiful clothes. It’s about connection, creativity, and celebrating those special relationships in your life. Our complementary jumpsuits are designed for mothers & daughters, aunts & nieces, best friends - anyone who loves to share their style and their stories.
But maybe you’re shopping solo and looking for something special just for you. Don’t worry! Each jumpsuit is crafted to stand beautifully on its own, and they are all sold individually.
We can’t wait for you to join our family adventure. Sign up below to be among the first to know when our collection launches!
With love and complementary outfits,
Butter & Birthday Cake
