Teen Vogue Senior Fashion News Director, Jane Keltner de Valle, after Chloe, Paris, March 2014. 
Weather still not warm enough to wear a summer blouse? Team a turtleneck sweater (cropped if you can pull it off) with an illusion skirt until the temperature rises sufficiently.
Recreate Jane's look (kind of):
Jonathan Simkhai Classic cropped turtleneck sweater,  Temperley London cashmere turtleneck sweater, ASOS Sweater with Roll neck, Rick Owens fine-knit turtleneck sweater, or Reiss Turin black turtleneck sweater (for when the weather does warm up!)
Tibi eyelet skirt
Mark Cross Scottie small satchel, Kate Spade New York Mini Pippa bag, or Delvaux Brilliant East/West
