“I don't want to be a queen. I want to be the queen.”
Margaery Tyrell is a fascinating character, she is feminine, soft, coquettish, young and vulnerable, at the same time strong, with an iron will, totally focused in her objective of becoming the queen, unstoppable and relentless. Natalie Dormer is doing a fantastic job portraying her character.
Michelle Clapton, the head costumer designer, had the task to conceive the dress that represents the sigil of the House of Tyrell, the rose and the thorns (how appropriated for Margaery own persona) the dress took six weeks to be completed. Notice the amazing crown that shows the thorny rose wrapped around the Baratheon antlers [Joffrey's sigil] showing her creeping influence.
