Fit: Designed to be relaxed, not fitted (except the pant waistband) and the fabric is very stretchy and forigiving. In between sizes? We'd size down in this style.
Length: Size 6 top measures 63.5cm (add 1.5cm per size). Size 6 pants measure 89cm (add 2cm per size)
Waist: Pants waistband is elasticated but designed to be snug (not tight!) with functioning drawstring.
Hips: So floaty and comfy! Not restrictive at all.
Bra advice: Sigh a sweet breath of relief, you can totes go bra-less mama! It is PJs after all. However, bra is somewhat recommended if you're wearing out of the house as loungewear ;)
Fabric: 95% viscose 5% spandex
