Yahoo! Lifestyle UK and Ireland has reported that the dresses worn by Katniss and Effie on their respective Capitol Couture portraits were inspired by the creations of popular fashion houses Alexander McQueen and Christopher Kane.
Sarah Burton OBE designed the red dress on the left, which is very similar to the one worn by Elizabeth Banks as Effie on the right. Burton also designed the wedding dress of Kate Middleton.
The one being worn by Jennifer Lawrence for the Capitol Couture portrait below (right) was similar to ones created by the Alexander McQueen fashion house. This is also part of the AW11 collection and was presented at Paris Fashion Week.
On the other hand, the one worn by Katniss during their victory tour (not the portrait) was also inspired by other Brit fashion house, which is Christopher Kane.
The fashion designer for Catching Fire is Trish Summerville (The Girl with the Dragon Tattoo).
