Consultant (such as Elle) can choose whether to wear scrubs or their own outfit (as long as it's smart etc). Another example of this was Adam Trueman who left in 2011. As for Lily, I was initially confused as well when she came in for her first shift as a registrar without scrubs on, but it seems that various female registrars in the past have done too, so perhaps it's just for female members of staff.

Cal's grey scrubs have never been fully explained - he was initially a locum registrar but must have become a permanent member of staff very shortly after his arrival. Additionally, Ethan is a specialist registrar whereas Cal is just a registrar. Jacob wears his outfit as he's a senior staff nurse as opposed to a regular staff nurse. Charlie doesn't even though he's senior as he's an emergency nurse practitioner.

Hope this helps!
