Planning- costume mood board

In my film there is going to be a montage of dates and in these shots i think that my two characters would look better in casual clothing as it shows that they are comfortable around each other which is what i want to show.
Another way of showing this may be the girl character wearing his hoodie which would be blue to represent a male colour and oversized to suggest it is his as he is bigger than her.
There may be some scenes where the characters are wearing more formal dressy clothing  in the shots where the situation is more serious, such as the date where he asks her to be his girlfriend and moves in with him.  Therefore, she could wear a red dress to represent love and romance between them.

The bottom left image is the type of clothing the event planner will be wearing as she is tied into the film through business. She will be wearing mostly black and some glasses as they usually suggest that a character is knowledgable which is what i want her to be portrayed as.
