Market Editor WSJ, Preetma Singh, after Diesel, NYC,September 2013.
A beautiful way to combine check + floral for spring: layer a plaid shirt under a pretty sheer top. 
Recreate Preetma's look (kind of):
Check shirt: Equipment Brett plaid silk shirt, Topshop Mix Gingham shirt, ASOS Bright check shirt, Just Female checked shirt, Etoile Isabel Marant Upton plaid shirt or Band of Outsiders Plaid easy shirt
Topshop Mono floral wrap blouse, Biyan Semonlina lace blouse, Tory Burch Jillian tunic (not sheer but it has the same pretty tones as Preetma's look),Yigal Azrouel lace check print top or Balmain printed linen-jersey top (these combine floral + check)
Rag & Bone/JEAN boyfriend jeans, Ksubi The Boyfriend jeans or Current/Elliott The Boyfriend jeans
