Here's some of my favorite "slutwalk" appropriate apparel from the internet.
The awesome "Ho" necklace is from esty... they have various other offensive necklaces.. including one with the "c" word on it, if you feel so inclined. The awesome vintage bralette is also from etsy, likely a 70s burlesque costume.
The cute lil lacy shorts are from ruche and the suspender tights are from modcloth... two things I would actually consider incorporating into my wardrobe!
The dominatrix leopard print heels are from asos.
And the boa is from your friendly neighborhood sex shop or halloween costume outlet.
