Meghan Markle’s Sheer Top Was a Sneaky Statement for a Royal Portrait Compared to, say, the engagement photo of Prince William and Catherine Middleton, which featured the bride-to-be in a pretty, conservative white day dress by Reiss, a British high street label, and framed her immediately as a newly accessible, down-to-earth kind of royal, Ms. Markle’s choice was labeled variously as “sensual” and “risqué.” But what it was, really, was a pretty big statement of difference. Ms. Markle has, since her engagement, become a singular mover of product — the coat she wore when she and Harry announced their plans sold out almost immediately — but the ball gown is in a different category.
