Ravenclaw students are selected for their house based upon their intelligence, logic, and creativity; even entering their Common Room requires answering a new and challenging riddle rather than memorizing a password. Their house founder, Rowena Ravenclaw, was the brightest witch of her age and believed that wit was, above all, mankind's greatest asset. Ravenclaws don't just love to learn, they also enjoy finding unique ways of doing things, and are often the inventors or discovers of new spells and techniques.
Personality-wise I've always considered myself to be a Ravenclaw, so when the Harry Potter movies came out I wanted to show my Ravenclaw pride in the midst of a sea of Gryffindors and Slytherins. When I first made this costume in 2005 there was no official merchandise for Ravenclaw or Hufflepuff, so I made the robe and pulled the rest of the costume out of my closet. The robe was a black bottom-weight fabric lined with a thin blue velvet which I sewed by hand using my own college graduation robe as a makeshift pattern. Sewing so much black by hand was horribly tedious, and I got so bored sewing it that the entire cloak ended up the messiest hack job I've ever done, even by my hand-sewn standards. The patch was a fan-made one I got online that was way too big, my wand was plastic and the tie I bought directly from the British manufacturer who made them for the movies but it wasn't the movie one and the wrong shade of blue. Over the years as official Ravenclaw items came out I have slowly upgraded this costume, and by 2010 I had an actual robe, sweater, tie, and wand and my old items went straight in the trash where they belonged.
