TV program like the Vicar of Dibley starring Dawn French has made dressing like a vicar even more acceptable and this had led to consumers wanting to dress up a vicar for their fancy dress party. The Vicar Of Dibley was the brainchild of Richard Curtis, famous for penning the likes of Blackadder, Four Weddings And A Funeral and Love, Actually.
One company offering a good range of historical fancy dress is Novelties 4 Parties â€" http://http://www.novelties4parties.co.uk/department/nuns-and-vicars-theme/
In recent years customers would have gone to the high street to visit their local fancy dress store but as more and more local specialist businesses have disappeared the growth of the online fancy dress stores have increased and with more consumers confident in the online security and delivery getting better and better customers are becoming more confident in buying fancy dress online.
For the ladies then dressing as a nun is very ironic especially as many of the available costumes are quite sexy and others are more traditional and iconic of the typical nun. While in common usage the terms nun and sister are often used interchangeably, properly speaking a nun is a female religious who lives a complemplative life of prayer and meditation
Current popular themes of fancy dress include:
Cowboys
Angel
Emergency 999
Little Britain
Heaven and Hell
1980's
Halloween

The choice is massive but at least dressing up as a Nun or a Vicar is different and therefore can offer benefits like not having other people likely to dress up the same at the party.
