Rochelle White told FEMAIL, "Kate's outfit has a look of sophistication to it. With the sheer black tights and finished off with a high neck jumper or dress, it gives off a classy look."
"Meanwhile with Meghan’s outfit I feel that this was a lot more relaxed and fun. With the purple on purple or burgundy colour it really compliments her skin tone.
Duchess Catherine's outfit saw her check out the Unit’s neuroscience research into how the environment and biology interact to shape the way in which children develop both socially and emotionally.
She also saw Unit's MRI Scanning Facility which is used to study the brain and chatted to members of Professor McCrory’s neuroscience research team.
Meanwhile, Meghan was greeted with cuddles as she caught up with her friends from the Hubb Community Kitchen.
She worked with the women, whose community was affected by the Grenfell Tower fire in which more than 70 people died last year, for several months and wrote the foreword for a cookbook featuring their recipes to benefit the project.
