This post will avoid spoilers from season 4, but may mention some details from the first 3 seasons – you have been warned!
Margaery Tyrell’s Signature Style
Rich Jacquard Fabrics and Light Blue
Deep V-Necks, Backless Dresses, and Cut-Outs
Another consistent feature in Margaery’s clothing is the presence of skin. Margaery’s style is decidedly more modern than her peers, with low v-necks and stylish cut-outs. To me, the drastic difference represents both where she came from (a different place with a different climate and social rules) as well as her tendency to put her arm around others when she speaks with them. I think Margaery uses touch to establish intimacy and trust when she speaks with others (though we will have to see how genuine it is!) For more about Margaery’s “armor,” this post is a wonderful read.
Big Hair (Full of Secrets)
Margaery’s long, curly brown hair is also one of the key elements to her style. She is usually seen with some or all of it pulled back. Like many other costume design choices in the series, the hairstyles worn by women represent where they are from and their character development. (For example, Sansa, from the north, begins wearing her hair in the southern style to blend in, and eventually wears it “like Lady Margaery.”)
