Jet Star from Danger Days: The True Lives Of The Fabulous Killjoys. In this cosplay I use the same boots and gloves as my Party Poison one, the jacket is sold out merchandise and the jeans are waxed black from Zara.
My favourite part of this is the red aiguillette (red shoulder cord) as even though the character wears one, it didn't come with the jacket, I was lucky enough to find a cheap one but can't remember from what website, to attach it to the jacket I cut a shoulder strap on an old shirt and asked my mum (I have no sewing skills) to sew them together.
This is by far the comfiest of my Killjoy costumes and maybe the one I feel the coolest in
Also the Comedian's badge from Watchmen was just something I added to the outfit 'cause it really suited it.
