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 - including the Hello Kitty x Spider-Man set.
