Yes, sorry, the "candidats" for romance will be more around Myriam's age and older (she's has a little daddy complex), the youngest would be Kimberley (if you count female romances).
But honestly, for William I can still change my mind, it's not set in stone, depending on how the flow of the scenes and writing goes, I'm always open to what will flow best.
Well, for the clothes, they are always dependent on the situation, Myriam won't be walking the town in a gala dress for doing her shopping. But that being said, some characters plot lines will have Myriam live more events with high-end clothes and dresses (like with Charles and Nubia).
