Well, I'm a Potterhead. I love the Malfoy Family and one of my best friends is totally in love with Bellatrix, so we decided to do the Black sisters <3
I made my costume and Bellatrix too, it was very funny, painting all the silver 'things' on the dress was relaxing!
Days of work 1, cost €0 (I already had everything I needed at home. Well, my mum had, I stole from her XD)
Bellatrix's dress 3 days of work.
