New York Fashion Week SS 2016....After Zimmermann

Hair inspiration, after Zimmermann, NYC, September 2015.

I guess this is sort of duct tape for hair but you could do something similar with a hairclip/barrette. A pretty vintage clip would look fab for evening with a messy hair bun. 

Recreate her look (kind of):

Hair clip - Mrs President & Co Thin barrette, J.Crew Wide metallic barrette, Made Hammered bar hair clip, Alexandre de Paris Thin hair clip, L. Erickson Volume barrette, Avigail Adam Anna Goddess hairpiece (this could look amazing), Jennifer Behr Venus crystal hair slide, Vintage hair barrettes, or Avigail Adam small olive clip

An updo that even I could master (I think!). Love a messy bun.
