Nightshade Cozy
Stay cozy. Stay dark.
Most cozy clothes are pastel and plain. We wanted the soft, zip-up, never-taking-it-off kind of comfort, made for girls whose rooms are full of candles, horror books and black lace.
So we made it dark. Moths, moons, roses and a bow on the back, on the plushest fleece we could find.

It has a relaxed, cozy fit. Check the size guide above for exact measurements. If you're between sizes, size up for a slouchier fit.

Reviews
From the Nightshade girls

🖤 Absolutely perfect
Finding a romper that doesn’t make me look like a toddler is a miracle. The cut is incredibly flattering, the material is solid black (not that faded gray-black), and it layers perfectly with my fishnets and platform boots. New wardrobe staple.

Comfy and spooky
Honestly, I was skeptical because rompers can be a hassle, but this one fits like a glove and has actual pockets for my crystals. It looks amazing under my oversized velvet cardigan. 10/10 would wear to a graveyard picnic.

Fall Depression Cured
I usually hate dressing for fall weather because I can’t wear my layers, but this romper is a lifesaver. It’s super breathable but still dark and edgy. Added a grommet belt and my silver chains, and the vibe is immaculate.
