The 2.0 TOG Adult Sleep Onesie has had a redesign, and now features a fit that is more suitable for feminine body proportions, large front pockets, thumb loops in the cuffs, and a detachable hood. Whilst the new Adult Onesie's runs true to size, we recommend sizing up for comfort, especially if you plan on layering underneath.
Please note: The table reflects the flat garment measurements. The new fit has been designed to standard women's sizing and is best suited to female (AFAB) body proportions.

I love this sleep suit so much! It’s so comfy and I love that it’s cotton, I wish I could wear it in public! The pockets are so handy and the long zip makes it so good for night breastfeeding.
