How cool is this picture of CP Mary, when she was pregnant with her twins? It appeared in German Vogue.
Meghan should embrace the pregnancy thing.
If she wore an empire line or a trapeze shape; she could wear a dress which stopped above her knees and showed her legs a bit.
Or she could wear them shorter as tops hiding and elastic waist on a pencil skirt.
I also think a fitted stretch top showing a bit of bump with a flared or Sunray pleated midi skirt and a tailored jacket would look cute.
