Billie loves a good matching set and chose a lime green option for the 2019 Reading Festival she preformed at. With a colour scheme straight out of Slytherin House, you will surely look unforgettable this holiday.
What to wear: A tie-dyed oversize t-shirt and shorts, and white high-top sneakers (Billie's faves are Nike Air Force 1 High PSNY). Pull your hair into two loose buns on either side of your head to finish it off.
