This one is Genevieve’s idea, it’s called a candy popping coat.
The basic gist is a coat/jacket but sans any buttons or Velcro. Instead to hold the two flaps of the jacket together there is provided a series of clips not unlike the little plastic hair grips that kids use. Ok exactly like the little plastic grips that kids use. The grips each fit though slits made in the flaps of the coat and lock together by snap fit. Pop pop pop.
The best part about this is that the grips can be changed according to the desired look of that outfit, be it a monsters high themed day or otherwise.
The pictures should explain everything. (Don’t be distracted by Jamie and the purple dog.)
