I wore this once a few years ago. The size is M. The shoes should fit if you're a 23-23.5cm! The Olaf plushie is not included. This is a set of the costume and wig shown in the photos. If you have a wig net, you can easily cosplay at Disney Halloween! The wig is quite misshapen, so you might want to style it! Some of the teardrop-shaped ornaments on the hem of the main costume have come off... Instant purchase is OK. No price reduction. No individual sales.
