However, this onesie may not be the best choice for those who need a smaller or larger size, as only medium is available. If you prefer more fitted or stylish sleepwear, this loose and playful design might not suit your taste.

Also, if you want something very lightweight for hot weather, the flannel material could feel too warm. In that case, you might want to look for thinner pajamas.
