Teen Vogue Senior Fashion News Director (and beautiful new mama!), Jane Keltner de Valle, after Christopher Kane, London, February 2014.
So many gorgeous sheer skirts around this season: how sheer, and what you wear underneath (big undies are definitely your friend!) is entirely up to you and your confidence. 
Recreate Jane's very pretty, feminine look (kind of):
Equipment Brett polka-dot long sleeve top, Topshop spot print shirt, American Apparel polka dot blouse, or Burberry Prorsum polka-dot linen shirt
Michael van der Ham gauze and brocade midi skirt, Tibi eyelet skirt, Cynthia Rowley midi skirt, ASOS midi lace skirt or Christopher Kane pleated lace skirt
Mark Cross Scottie small satchel, Delvaux Brilliant East/West or Tom Ford Large Natalia kidskin bag
