Do They Run Small?

Cute Asian-style sleepwear can run a touch smaller than standard US sizing. If you are between sizes, or you like a roomier lounge feel, **size up**. The elastic waistband gives flexibility, but the size chart is always the most reliable guide. Once you know your size, it's the same across the [pajama collection](https://snuggleheaven.shop/collections/pajamas) - including the [Hello Kitty x Spider-Man](https://snuggleheaven.shop/products/hello-kitty-x-spider-man-pajama-pants) set.
