Can you win a battle to the death in ancient Rome? Feel like you were a might warrior standing beside Julius Caesar in a past life? Then a gladiator fancy dress costume could be great for you. This can fit in to a toga theme fancy dress party or many other historical themes.
There are also some great gladiatoress fancy dress costumes for women. Not sure if they are historically accurate though!
If you want something on a similar theme but a little bit more refined I like the look of the roman centurion fancy dress outfit.
A roman gladiator fancy dress costume is a made of a few different items. First of all a gladiator would wear different pieces of body armour. So you can have an impressive looking chest plate, a shield which is worn on the arm, leg arm which goes on the shins and some armour which straps round the forearms. The armour that goes on the arms leather is a nice look and you can pick up some nice leather bracelets and straps which go well with this kind of costume.
The helmet is, in my opinion, the best part of this costume. Make sure to pick up a good fancy dress roman helmet. The key feature of this is a large piece of plummage, typically with red feathers, which sprouts out of the top of the helmet. The helmet itself is usually golden.
One the feet some leather sandals with straps running up the shin almost to the knee make for a great roman soldier fancy dress.
