When is the show going to be? Is it going to be a daytime affair or an evening one? Bear in mind that if you opt for an evening time show, ideally you should be able to provide entertainment for a couple of hours (including an interval). Alternatively, it could be a shorter show staged during lunchtime and maybe repeated a couple of times throughout the day to ensure maximum exposure -i.e. everyone who wants to see it can. This sort of show sill take less organising and works well if the audience is just going to be fellow pupils at school.
The venue of the show might dictate the date and the length of the show. If it is going to be at school, book the hall as far in advance as possible. Consider whether it will be possible to hold rehearsals there in the run up to the show. If you are planning the venue to be outside school you will need to check with a teacher that the venue has the appropriate insurance for the show. You will also need somewhere to practice. You should also bear in mind that there will need to be some sort of space to keep the outfits in and a place for the models to get changed. A separate area for boys and girls will be needed. If possible this area will be private and warm
