Helena Bordon, before Tibi (wearing Tibi I think), NYC, September 2015.
On a grey spring day it is hard to imagine weather warm enough to wear a sleeveless top and sandals... but it will come (we hope!). The simplicity of Helena's outfit — clean lines, neutral colours, beautiful shape — is perfection. 
Recreate Helena's look (kind of):
Tibi Double Crepe Sable curved panel top + Tibi Double crepe sable wrap skirt 
Summer flat sandals — Tod's Piat maxi fringed sandals, Michael Kors Collection Candice leather sandals, Vince Mailin flat sandals, Tod's Fringed leather sandals,  Franco Sarto Gia Sandal, Ancient Greek Sandals Satira sandals, ASOS Foxtrot leather tassel sandals, Topshop Flora Toe post sandals, Barneys New York knotted-thong sandals, or Bottega Veneta Embroidered woven leather sandals
