The Tyrell's are some fashionable people, usually opting for flowing clothes with, of course, lots of floral patterns. First, here's an outfit I made on Polyvore for Margaery.
Below is an outfit I've wanted to do for awhile since I rarely "dress up," it's mostly just t-shirt and jeans for me. I don't care if peplum is way out of style nowadays, I still love it and think it's a great staple piece for any closet.
Anywho, here is the outfit I made using stuff from my own closet!
peplum top // express | floral skirt // charlotte russe
flats // H&M | necklace // forever21 | rings // charlotte russe
