A piece that I really love is the button up dress (or zipper dress) because it can be worn in different ways. Wear it the way it's meant to like a dress, a vest or cardigan like I did today and some can even be worn a as a top or tunic.
This dress that I'm wearing today I bought years ago from Topshop and I love it. I wore it as a vest over my basic grey top from Asos and paired it with my lace shorts from Noisy May. I added my favorite earrings from Pieces (I actually bought these at the same time as the shorts in Denmark last year), I added a studded choker and a pair of studded booties from H&M. The rings I made myself.
