Witches hat, dress and Velcro fastening net skirt. The band on the hat and the skirt are reversible so you can choose to have purple or orange accents.
I got this for my daughter last year and cannot complain. As well as trick or treating and a Halloween party (where it fot covered in chocolate and face paint- washes fine by the way!) she wore it to a Halloween event at a soft play centre. Some of the kids seemed a bit restricted in their more elaborate costumes but she was comfortable and could move freely on the play equipment in this.
They also sell a basic black witches outfit for £2.40, could be a fun little project to get that and add your own embellishments.
