Hoolies sizes are designed to be generous and do not conform to typical chain store sizes. But don’t let that complicate your purchase decision – we’ve made it simple by providing a size chart for each item.

Here’s what to expect from Hoolies Sizes:
Onesies
These are designed to have a larger fit.
Why? With plush velour in winter, which doesn’t have the same stretch as knits, we provide extra length for easy bending of limbs and free movement for sleep and play.

For consistency, our regular customers have requested that we maintain the same sizes across all season items. Please take a moment to measure your child from the shoulders to the ankles and match it to our size chart.
