Peony Lim, before Valentino, Paris, March 2012. 
It is wedding season in the Northern Hemisphere and with that comes the mild  full-blown panic over what to wear...and particularly in the UK, what to wear on your head! If etiquette dictates that you must wear something on your head but you aren't keen on a hat, try a simple tulle fascinator like Peony's or a lovely floral garland like Natalie's (in the post above this one).
Recreate Peony's look (kind of):
Haute Hippie peasant blouse, Joie Alpina blouse, Ruffle chiffon shirt from Peony's online store or Moschino ruffled collar tulle top
AG Adriano Goldschmied Stilt cigarette leg jeans, Rag & Bone/JEAN The Skinny Jeans or M Missoni Linda mid-rise jeans
Miu Miu glitter platform pumps or pointed pumps
