About Us

Hi and welcome to my atelier of love, joy, unicorns, and rainbows! I'm Nina, and this shop is my creative passion project. I love colorful things, playful designs, and painting colors onto otherwise bland everyday objects. I started Sillie Pants in 2020 as a way to make colorful gym clothes for myself, and finally launched the current version of the online store in 2024. I have been based in New York City for the past 10 years, but have my roots in Japan.
My mission through Sillie Pants is to create the most ridiculously vibrant and colorful activewear that makes you happy by wearing it and puts a smile on your face when you look into the mirror.
All prints are designed by me on my iPad, with much love, by hand. They are then printed and manufactured by our printing partners that we picked carefully based on product quality and sustainable practices.

Sustainability
Beyond designing vibrant and colorful activewear, we are committed to making mindful choices that support both people and the planet. That’s why we partner with manufacturers who share our values, prioritizing sustainable practices, recycled fabrics, and eco-friendly processes whenever possible. Our made-to-order approach helps minimize waste and reduce overproduction, contributing to a more sustainable future. Read more about sustainability

Quality
As much as we want the products to be colorful, vibrant, and fun to look at, the most important thing is that they are comfortable to wear and are of good, durable quality. We partner with production partners that we selected carefully based on high-quality fabrics and premium printing techniques using non-toxic material.
