Lady Queen   +  white shirt

Paris Couture Fashion Week AW 2013... Sophia
Sophia, after Ulyana Sergeenko Couture, Paris, July 2013.
I have just been on a trip to Southern Spain where it was very warm at times (38° Celsius!) — this outfit would be perfect for those temps (perhaps with flats rather than platform pumps) particularly if you are wandering in and out of air-conditioning. Stylish, smart and comfortable.
Recreate Sophia's look (kind of):
3.1 Phillip Lim draped pants, ASOS peg pants in linen, Mother of Pearl tapered pants, or YMC Boyfriend chino
PJK Patterson J. Kincaid lounge shirt, Vince Raglan half-placket shirt, Haider Ackermann silk-satin shirt, or Joie Tamarine top
Sensi Studio Toquilla panama hat
