I ordered Snow and now I never want to wear real clothes again. The fabric is so much plusher than I expected for the price, and the little hood with the crown detail genuinely made me laugh out loud when I put it on. My friend ordered Cinderella two days later.
The Once Upon Cozy Princess Onesie is cut relaxed and roomy on purpose, so most people order their normal size and get a comfortable lounge fit. Please check the Size Guide before ordering and compare the measurements against something you already own and love.
If you want extra room to curl up in, or you are between two sizes, size up. The ankle and wrist cuffs are elasticated so a looser body still stays put.
Your Once Upon Cozy order arrives ready to wear. Each one includes a single full-length hooded princess onesie in the size and princess you selected at checkout, with the signature crown-detail hood, side pockets, and front zip closure.
All orders from Once Upon Cozy process within 1 to 2 business days and standard shipping arrives within 5 to 9 buisness days for most countries. Delivery windows can shift with your local carrier, holidays, and weather.
Every purchase is backed by our 30-day money-back guarantee, so you can try the Princess Onesie completely risk-free.
Tiana in deep emerald, Belle in warm butter gold, Cinderella in sea-glass blue, Ariel in soft blush, and Snow in midnight navy with silver stars. Each one is cut from the same ultra-plush fleece with a crown-detail hood, so the only hard part is choosing.
Most novelty onesies are thin, scratchy, and fall apart after two washes. Here is how ours compares.

I ordered Seraphine for a movie night, but now I reach for it every evening. The fleece feels thick and wonderfully soft—so much cosier than I expected.
After four washes, mine has kept its shape and I haven’t noticed any pilling. The little silver stars on Noctis look even prettier in person than they do in the photos.
I first ordered Marigold for myself, then bought three more for my sisters. We all wore them on Christmas morning, and I love how our photos turned out.
Each onesie is made from a brushed plush fleece blend that is soft on both sides, warm without being heavy, and holds its shape wash after wash.
All five are the exact same cut and fabric, so it comes down to color. Seraphine is deep emerald with gold trim, Marigold is warm butter yellow, Opaline is sea-glass blue with pearl detailing, Rosalind is soft blush with rose gold, and Noctis is midnight navy with silver stars.
Yes. The brushed fleece traps heat the way a good blanket does, and the full-length cut means no cold gaps at your ankles or lower back. Most people find it warm enough to drop the thermostat a couple of degrees.
We recommend checking our Size Guide before ordering and comparing the measurements with something you already own. The fit is intentionally relaxed, so if you want extra room to curl up in, consider sizing up.
Try it for 30 days, and if you are not happy for any reason, we will refund you in full under our 30-day money-back guarantee. No risk on your end.
