Luna Lovegood comes into the Harry Potter series in the fifth book/movie, The Order of the Phoenix. I know, I know- you were expecting this. Everyone wants to be quirky and weird and cool. But NO, that’s not all! She’s so much more than that! Her clothes aren't just randomly strung together to look as unflattering as humanly possible: they are exactly like her.
Luna Lovegood is the same inside and out. She is dreamy and colorful but still wholesome and earthy. Her clothes aren't obnoxious or random, but just rather unusual. The unusual part is usually what people see first, but if you look past that, Movie Luna always looks like her voice and personality.
Here is an example where Luna sports some funky, electric blue leggings with a printed skirt, topped off with an eclectic pink jacket. She pairs all of this with a pair of blue, striped socks and her purple, floral Doc Marten style shoes. I admire how she wasn't afraid to mix and match patterns and colors. While some may see this outfit as crazy obnoxious, I see it as Luna. This is Luna's personality and I think it's beautiful that she isn't afraid to show it.
