Danish model Charlotte Lindvig, after A Show, NYC, September 2015.
Love Charlotte's post-show messy hair with the paint-splatter effect button down shirt. Has me imagining an artist from the 70's taking a break from the studio... Charlotte's solid white painted nails are pretty fun too! Reminds me of painting mine in liquid paper during boring classes. A DIY project for an old chambray shirt you have in the back of your wardrobe... I think a fluro paint splatter would look really cool.  
Recreate Charlotte's look (kind of) 
Denim skirt — Current/Elliott The High Waist stretch-denim pencil skirt, McGuire Denim Marino skirt, J.Crew Denim front-slit skirt, ASOS Denim split front skirt, Madewell denim midi skirt, Rollas Denim pencil skirt, or 7 For All Mankind Exposed Button Long skirt
p.s. Stella McCartney's paint splatter skirt for littlies (good inspiration for DIY paint-splatter colours).
