More details on the website, but here is some information on sizing:

Our kigurumi will fit most people

Kigurumi are made to be loose fitting and will accommodate adults and children who are at least five feet tall. However, if you're taller than six feet the wrist and ankle cuffs might not make it all the way to your wrists and ankles.

XL Kigurumi are designed to fit people over 6 feet 2 inches tall. The Regular size is best if you're under 6 feet tall. If you're in between 6 feet and 6 feet 2 inches, either size will fit, but the XL size might be a slightly better choice.

The bagginess of our Kigurumi means there's a lot of room in the chest and waist. If you're concerned with fitting into one of our Kigurumi, the limiting factor is usually your shoulder width.
