FEATURED ONESIE FOR 2025
Handmade in San Francisco. One-of-a-kind. Unisex. Sexy AF. Made with Mushrooms. Customizable by Local Artists.
This isn’t just a onesie. It’s a revolution in denim. The Mushroom Acid-Washed Onesie by The Onesie King is handmade in San Francisco, naturally dyed with wild-foraged mushrooms, and acid-washed to earthy perfection.
Crafted from rare deadstock flocked denim with just the right amount of stretch, each piece is completely unique — no two washes, fades, or fits are ever alike. This gender-free jumpsuit hugs in all the right places, feels broken-in from day one, and turns heads from farmers markets to full moon raves.
