Since Miu Miu made them hot last summer, collar accessories have been a part of many designers collections. These are by Dime Piece Designs. To DIY these, you´ll need a white collar cut out from a second hand shirt and a textile marker or sharpie. The crosses on the black shirt collar have to be printed with fabric print colors. Pigment dyes are best as they hold enough pigment for these white-on-black print projects.
